Does the VAZ 2109 carburetor fill spark plugs? you are not alone. the problem is solvable

Quite often, VAZ-2109 carburetor owners have to solve a problem, especially in winter, the essence of which is the so-called filling of spark plugs with fuel. If gasoline gets on these elements, the car simply will not start, despite the fact that the day before it worked properly and never let the driver down on the road.

Why does the VAZ-2109 carburetor flood the spark plugs with the onset of cold weather? It is this question that should be answered before you begin to fix this problem yourself.

Causes of oil on spark plugs

If the candles are covered with oil, then first of all it is necessary to determine exactly which part has the most of it. Many car owners are faced with a situation where only the threads and body are coated with lubricant, while the electrodes are dry and have a normal color (light brown). But it also happens that the entire base ends up in oil.

At the same time, in addition to traces of lubricant on the spark plugs, a malfunction with the engine manifests itself in other ways - deterioration in dynamics, increased exhaust smoke, oil burns. In order for it not to be the cause, it must be eliminated.

Most often, the appearance of grease marks occurs due to wear and damage:

How to understand that the candles are flooded

First of all, you need to define the concept of “drenched candles”, that is, what is it? One of the main operating cycles of a gasoline internal combustion engine is the supply of a fuel-air mixture to the combustion chamber and its subsequent ignition. When, for some reason, the spark plug does not light it, this is called “flooding the spark plugs.”

And all because a large amount of fuel gets into the electrodes and the spark plug body. And the more fuel that gets there, the more difficult it is to ignite it, although in practice this is almost impossible until they are dried.

Most often this happens during the cold season, during significant frosts or simply during cold snaps. As drivers say, “in the cold.” During such a period, there is a heavy load on the battery and if it is weak, then there is always the possibility of flooding the spark plugs. That is, the driver tries to start the car two or three times, while the battery is discharged and the spark plugs are filled with gasoline.

However, spark plugs can be filled with more than just gasoline. two other process fluids can get on it - engine oil and coolant (antifreeze or antifreeze).

Indirect signs that the spark plugs are filled with engine oil are the following situations:

rapid decrease in oil level in the engine crankcase;
Unstable engine starting, and at any time of the year;
decrease in the dynamic characteristics of the car, poor acceleration, drop in power;
Unstable engine operation at idle speed;
"triple" of the engine.

It is necessary to understand that the listed signs may indicate other breakdowns in the engine, so it is better to unscrew the spark plug/s from its seat and visually assess the condition of its electrodes and insulator. Moreover, it is advisable to check both for the presence of burnt oil and for the general condition. Much can be understood by color.

Similar signs will indicate that the spark plug is filled with coolant (antifreeze). In this case, there will also be a drop in engine power, a rapid drop in the coolant level, and the appearance of white carbon deposits on the spark plug electrodes and/or its insulator. You may also notice the appearance of white smoke from the exhaust pipe.

What to do if the candles are flooded?

If the spark plugs are flooded and you need to start the engine as soon as possible, then you can forget about all the above reasons and start the engine using several methods.

This method is prescribed in many operating instructions. To do this, the spark plugs are unscrewed using the appropriate wrench and dried. For drying, you can use a regular gas stove. After the candles become dry, wipe them with a dry cloth, thereby eliminating new carbon deposits and screw them into place.
The second option also came to us from old carburetor cars. The essence of this method is to dry the candles without dismantling them. The method works equally on both injection and carburetor engines. The gas pedal is pressed all the way to the stop, and the engine is spun up using the starter for 10 seconds. Thus, the gasoline supply is shut off, and the engine cylinders begin to be purged with air alone. In this short time, the candles have time to dry quite well. During the purging process, you must release the gas pedal. After this action, the engine can usually be started without problems.
If all else fails, check for spark. To do this, one of the armored wires is pulled out and leaned against the cylinder head by 4-5 millimeters. Have an assistant turn on the car's starter for a short time. If a blue spark jumps between the wire and the cylinder block, then the spark plug is serviceable. However, there are spark plugs that may not work on a particular type of vehicle. Try installing new spark plugs. In most cases, this method almost always works. If there is no spark, then the fault lies either in the armored wires, or in the Hall sensor, or in the switch itself and the ignition coil.
If the first start of the engine is unsuccessful, then you need to wait a certain pause. Usually it is 5-10 minutes. This is done in order to avoid flooding the candles. As for carburetor cars, experienced drivers recommend making the first start without closing the throttle. To do this, start the car without choke and vigorously press the gas pedal to give it the opportunity to warm up the combustion chamber. After this, the damper closes, and it is not recommended to touch the gas pedal.

These methods allow you to start the engine only when it is urgently needed. If your VAZ spark plugs flood quite often, then it is necessary to diagnose the fuel supply system and, if possible, repair or adjust it. Do not tighten under any circumstances, as if there is a non-combustible residue, the oil scraper rings will fail.

That's all. Perhaps, the whole range of measures is listed here that will help you revive and start the engine in the cold, even with flooded spark plugs. This event is carried out independently, so any driver should know about it.

Solving the issue in several ways

Radical (cardinal) decision

If the VAZ 2109 is filled with spark plugs, the main question is what to do? And we do the following:

We go to a car store with an old spark plug for a sample, select new spark plugs in the image and likeness of the old one, and completely replace the entire set
When choosing, beware of fakes; do not buy too inexpensive candles that also do not have original packaging.
It is also recommended to take a close look at the new spark plugs and make sure there are no packaging defects, including the design, defects in the electrodes, ceramic base and inscriptions on it
Defects in the thread or an easily removed or unscrewed O-ring also indicate a fake.
However, the engine can stall somewhere on the road, far from “civilization” and shops
If you look from the other side, replacement is an additional expense, and usually very inappropriate
Let's move on to a more gentle, budget option so that the price does not hit your modest budget

The most economical solution

How to solve the problem without spending money:

To save money, flooded car spark plugs need to be unscrewed and “heated”; a gas burner or a homemade torch will help with this as a last resort.
Your task in this case is not just to heat the candles, but to warm them up until red, or at least with fire to completely clean them of carbon deposits, as well as traces of gasoline
This method has negative sides; many experts claim that after this the candles will not last long, because such heating can damage the ceramic core of the candle itself
In addition, a matte oxidation film appears on the electrodes, which it is advisable to remove with fine sandpaper

It’s up to you to choose, I’ll tell you, when you are far from the store and, as luck would have it, you need to go urgently, you don’t care about sentiment.

A quick solution from craftsmen

Instructions from folk craftsmen:

In the absence of new spark plugs at hand, there is also nothing to “ignite” with, then you can use the old, so to speak “old-fashioned” method, which often helps solve this issue
Flooded spark plugs simply need to be dried using a starter.
To do this, do the following: depress the gas pedal completely, then rotate the engine for a while, only using the starter
The influx of fresh air allows the surfaces of the candles to dry out.
Due to the fully open throttle, gasoline will not flow into the combustion chambers
After drying, the engine should start, although not on the first try.
The disadvantage of the “old-fashioned” method is that there is a high probability of completely draining the battery
And after that, another driver can help you, who will agree to “give your engine a light” from his
Or a spare battery, but the likelihood that you will have it at the right time is zero
Now it is clear to the owners of the VAZ 2109 why the candles are flooded, as well as ways to cope with the problem

That’s all, I hope the material in this article will help you out in difficult times, and you won’t get confused; in addition, it’s worth watching the video lesson, since a person perceives and remembers information better through a picture.

The oil pressure light came on

If your oil pressure warning light comes on while driving, you need to stop immediately. Further driving may result in serious engine damage. After stopping, perform the following diagnostics:

– check the oil level on the dipstick;

– it is possible that oil of inappropriate viscosity has been filled in - replace it;

– remove the oil pan and check the oil receiver mesh (may be clogged) and the pressure relief valve for distortion, clogging or weakening of the spring;

– inspect the fuel pump diaphragm - if it is damaged, gasoline enters the oil, thereby diluting it;

– check the oil pump - it may be faulty due to wear on the gears;

The engine does not start in cold weather, reasons

But flooding of spark plugs, unfortunately, is not the only factor that negatively affects the engine starting procedure at low temperatures. Every car owner should know about the most common of them - familiarity with the cause of problems of this kind often allows one to prevent the very possibility of their occurrence.

Problems with flooded spark plugs can occur when purchasing and installing a low-quality product. What we can recommend to car enthusiasts is that you should not choose consumables and spare parts for your car based on thoughts of maximum savings; purchasing a quality product at a higher price can often save you from many problems that arise during operation.

A weak spark can also occur if the spark plugs are heavily contaminated with carbon deposits, but the spark produced from them is not able to ignite a cold fuel-air mixture that does not contain flammable vapors.

High-voltage wires are damaged, how to check and fix them

You can also fill the spark plugs with gasoline if the high-voltage wires are damaged. The reason is that faulty wiring can produce an uneven spark.

poor quality fuel

The quality of the fuel is a very important factor on which the evaporation process depends. Practice proves that even at normal temperatures some types of fuel do not exhibit normal combustion; there is no need to say that at subzero temperatures they will evaporate and ignite.

Experts recommend paying attention to the quality of the fuel your car is fueled with and its suitability for the season. For use in the cold season, preference should be given to gasoline with the highest octane rating allowed for your car engine.

malfunction of the power system, how to check and fix it

Difficulties in starting a cold engine can also be caused by faults in the power supply system. A negative impact is caused by clogged or worn injectors, which, as a result of existing defects, can supply the wrong amount of fuel. Naturally, such violations will cause the candles to burn out.

To eliminate the problem, it is recommended to systematically monitor the condition of the engine components and systems, and eliminate any deviations noticed in a timely manner. Maintaining the power system involves regular cleaning and adjustment to the recommended settings.

Problem solving

How to fix this problem? The operating manual for modern cars says something like this: “If the spark plugs on the injector are flooded, you need to unscrew them and dry them thoroughly.” In this case, the starter must be cranked for 10-15 seconds after removing these elements. Next, the dried spark plugs are inserted back into their original place, and after that the engine starts. This is the way the car manufacturer offers us to fix the problem.

But there is another, popular, way to eliminate this problem. If you fill the spark plugs when they are cold (injector), before unscrewing and drying them, you should start the engine as follows. For injection internal combustion engines, the gas pedal is pressed to the floor all the way, the starter cranks the engine for about 10-15 seconds, then the pedal is released. In most cases, this helps to start the car. The essence of these manipulations is to blow air through the “wet” spark plugs (in this case, the fuel supply is completely shut off).

Replace spark plugs every 30,000 km, even if they are still in working order: old spark plugs can increase fuel consumption.

When preparing for winter use, replace the spark plugs with new ones.

Regularly check the connections between the high-voltage wires and the spark plugs and ignition coil. Keep high-voltage wires clean by periodically wiping them with a cloth. Contamination on wire insulation can cause current leakage

Use the following spark plugs:

A17DVRM, A17DVR or FE65CPR.

You will need: spark plug wrench, bit, round feeler gauge, spark plugs.

This is what a spark plug wrench with a bit looks like.

1. Disconnect the wire from the “–” terminal of the battery.

2. Remove the tip from the spark plug.

When removing spark plugs, be careful - if the engine is hot, you may get burned.

Do not pull on the wire. Apply force to the tip.

3. Clean the spark plug and the area around it from dirt so that when turning the spark plug out, no dirt gets into the cylinder.

Carefully move the spark plug with a wrench and then remove the spark plug completely by hand.

If the spark plug is difficult to turn out after the first start due to carbon deposits formed, do not apply much force so as not to damage the threads in the cylinder head. Lightly twisting and unscrewing the candle, gradually turn it out of the head.

Why does fuel flood the spark plugs in the injector?

If the spark plugs are flooded, then among the reasons, the condition of the piston system should be put in first place, because with ideal compression, the engine should start even with minimal spark values. However, only a new car can have such compression, while a used car already has some wear and tear. After only three years of operation, a VAZ car begins to suffer from this disease when fuel enters the injector.

It is typical that fuel can get onto the spark plugs in winter even in serviceable cars as a result of the system’s interaction with cold air. But in the summer, this problem in the vast majority of cases occurs if something is wrong with the car. The ignition control unit malfunctions - when a command is given to increase the fuel in the injectors, the fuel supplied in a large volume does not have time to ignite, hence wet spark plugs and other troubles. This applies to injection engines; for carburetor cars, in the absence of an ECU unit, this situation arises due to insufficient compression, and this directly depends on the condition of the piston group.

It is worth mentioning another problem when the spark plugs are stained with oil and the engine operation is inconsistent. There is an increased waste of expensive oil, problems with idling and “triple” of the engine. Among the reasons, we can name, first of all, the same wear of the piston group, increased oil pressure in the crankcase, failure of the valve stem seals and cuffs.

Seven reasons to fill candles when cold

If you decided to start the engine, but nothing happened, and instead you found spark plugs stained with gasoline, then this could happen for the following reasons:

1. Insufficiently charged battery. Even if at positive temperatures the battery coped with its tasks without problems, the onset of frost could radically change the situation. It is enough for the battery to be discharged by 50%. Even with this indicator, there may not be enough power to start the engine.

2. Cylinder wear. A worn-out engine cannot run perfectly, so it is not surprising that new engines have insufficient cylinder compression. In combination with other factors, this can lead to flooded candles.

Compression measurement

3. Old spark plugs. It is not for nothing that this part is consumable and requires regular monitoring and, if necessary, replacement. If you do not change the spark plugs for a long time, then defects appear on them, which can prevent spark formation, which is so necessary to start the engine.

4. Malfunction of structural elements of the ignition system. Faulty wires and soured contacts can be one of the reasons that caused spark plugs to flood.

5. Poor quality fuel. This does not mean that you were deceived and sold bad gasoline. The point is that in winter there are a number of factors that can negatively affect the quality of fuel.

For example, the formation of condensation in the fuel tank and its entry into gasoline. As a result, the fuel does not ignite at the right time, which becomes one of the reasons for “wet” spark plugs.

6. Unsuitable engine oil. If we are talking about winter, then you need to use oil with a viscosity that will not load the engine, otherwise this will become another factor creating conditions for flooding.

7. Accumulation of carbon deposits in the combustion chamber. Short trips in the city do not allow the engine to “breathe”. As a result, carbon deposits form, which settles in a thick layer on the walls of the combustion chamber. The mobility of the piston rings decreases, and with it the compression in the cylinders. As a preventative measure, it is necessary to run the engine at high speeds. Sometimes, to return the piston rings to mobility, special flushing of the system is required.

Carbon deposits in the combustion chamber

Sometimes it happens that there is a spark and the starter rotates normally, but gasoline still pours out. In this case, it is necessary to carry out diagnostics to determine the serviceability of the spark plugs. In rare cases, the problem may be in the ECU itself.

What should a VAZ-2109 car owner do if the spark plugs are filled with fuel?

VAZ-2109 carburetor car owners can solve the problem of “filling” spark plugs in two ways:

You can, of course, unscrew one of the spark plugs and buy exactly the same element, fully assembled, in specialized stores or at automobile markets.
Take advantage of a more budget-friendly option and solve this problem yourself. This process is quite simple, so every car owner can cope with it if replacing and cleaning the spark plugs is carried out in stages:

all candles must be carefully unscrewed from the so-called “sockets” and ignited under the flame of a gas burner, holding them with ordinary pliers;
these elements need to be heated until the metal turns red in order to completely remove carbon deposits and any contaminants;
after warming up, you need to use fine-grained sandpaper to get rid of the film that forms during the oxidation process around the connectors;
Then all that remains is to screw the spark plugs into their original place, and the replacement process can be considered complete.

According to many experts, although such a process is considered economical, it will not help to operate thoroughly heated and cleaned components for a long time, since this process quite often damages the candle core, the basis of which is fragile ceramics. Therefore, if car owners decide on this replacement method, they must understand that, most likely, in the very near future the spark plugs may fail again, and they will have to repeat the whole process again. It is best to immediately buy a new set of components that match the markings and use them for their intended purpose.

After reading this article, every owner of a VAZ-2109 carburetor will be able to independently replace the spark plugs, clean and dry them, and, of course, install them in their original place. Such an event will not take much time, and if questions or difficulties arise during the replacement, you can simply watch a video tutorial on the Internet resource, which will further simplify the replacement of failed elements.

Why are the candles flooded?

Let's first look at the reasons why the spark plugs on the injector are flooded. To do this, consider the operation of a car starter.

Thanks to the operation of its pistons and valves, a mixture of gasoline and air is supplied to the combustion chamber, which is ignited by a spark generated by the spark plugs. After ignition, the starter turns off. Thanks to ignition, the engine cylinders start working. To successfully start the engine, you need a working starter, a powerful battery and a favorable ambient temperature.

At low temperatures, gasoline does not mix well with air. It is known that frosty air contains more oxygen. An increase in oxygen content requires the supply of more gasoline. The vehicle's electronic control unit sends a signal to the fuel injectors, which increases the fuel supply. Thanks to the starter, compression is created in the cylinders and at the same time a spark is formed to ignite the fuel mixture. But since the compression does not meet the standards and the spark is weak, the incoming gasoline will flood the spark plugs, preventing the mixture from igniting. This is the reason why candles are poured in cold weather.

The formation of a spark is influenced by the following factors:

Gasoline quality. It should not contain many impurities and dirt, as this will affect the operation of the injectors.
Engine wear. If the engine pistons are worn out, they do not create the necessary pressure and fuel may flood the injector.
Quality of candles.
Quality of injector and carburetor.
Battery power: You should monitor its charging.

If the compression is ideal, the engine will start even with minimal impulse and fuel fluid will never fill the injector. But only a new car can boast of such compression. If a car, for example, such as a VAZ, is more than three years old, gasoline fills the spark plugs on the injector more often.

What are candles

Let's look at the device so that you can understand more clearly what we are dealing with:

The spark plug housing is screwed into the cylinder head
The insulator material in it is heavy-duty technical ceramics
From the inside, a central electrode is fixed on one side and a contact rod on the other in the ceramic part of the spark plug.
And between them there can be a resistor that suppresses radio interference
Its side electrode is welded to the body

The design differences between the spark plug insulator and the central electrode itself make it possible to divide them into hot or cold:

Hot candles are distinguished by a large surface of the insulator, which protrudes into the chamber and is heated by burning gases, and the transition zone from the insulator to the outer shell, on the contrary, is small
Cold ones have an increased heat removal zone, so their working surfaces heat up less
The heat number expresses the ability to accumulate heat
Therefore, in order to choose the right replacement spark plug, you need to use an interchangeability table or a proprietary catalog, because the manufacturer has its own catalog system

Which spark plugs are best for Oka

Scheme of the contactless ignition system of the OKA VAZ-1111 - 1113 car: 1 - ignition switch relay; 2 — ignition switch; 3 - fuse block; 4 - switch; 5—sparking torque sensor; 6 — ignition coil; 7 - spark plugs.

The ignition system is contactless. Consists of a spark torque sensor, switch, ignition coil, spark plugs, ignition switch and high and low voltage wires. Spark timing sensor - type 5520.3706 (until 1989, a type 55.3706 sensor was installed) with built-in vacuum and centrifugal ignition timing regulators. It sets the moment of spark formation depending on its initial setting, the number of revolutions of the crankshaft and the load on the engine. Reading of control pulses is based on the Hall effect. There is one pulse for each revolution of the crankshaft (two for each revolution of the camshaft). The initial ignition timing angle for the VAZ-1111 engine is −1 ±1° BTDC, for the VAZ-11113 - 4±1° BTDC. The switch - type 3620.3734, or 36.3734, or HIM-52 opens the power circuit of the primary winding of the ignition coil, converting the control pulses of the sensor into current pulses in the ignition coil. The switch is checked with an oscilloscope using a special method; if a malfunction is suspected (interruptions in engine operation, shots in the muffler), replace it with a known good one. Do not disconnect the switch connector while the ignition is on - this may damage it (as well as other components of the ignition system). The ignition coil is two-terminal, dry, type 29.3705 - with an open magnetic circuit, or type 3012.3705 - with a closed magnetic circuit. Data for testing: resistance of the primary winding at 25°C - (0.5+0.05) Ohm, secondary - (11 ± 1.5) kOhm. The insulation resistance to ground is at least 50 MOhm. Spark plugs - type A17DVR, or A17DVRM, or their imported analogues (with noise suppression resistors with a resistance of 4-10 kOhm). The gap between the electrodes should be within 0.7-0.8 mm (checked with a round wire probe). High-voltage wires - type PVVP-8 with distributed resistance (2000±200) Ohm/m or PVPPV-40 with distributed resistance (2550±270) Ohm/m. Do not touch high-voltage wires while the engine is running - this may result in electrical injury. It is also prohibited to start the engine or allow it to operate with an open HIGH VOLTAGE circuit (crushed wires) - this can lead to insulation burnout and failure of the electronic components of the ignition system. Ignition switch - type 2108-3704005-40 or KZ813 with an anti-theft locking device, blocking against re-starting the starter without first turning off the ignition. When the key is turned to the “ignition” position, voltage is applied to the control input of an additional relay type 113.3747-10, which, in turn, supplies voltage to the ignition coil and switch. Thus, the contacts of the ignition switch are relieved.

Flooding when there is a spark and the starter is rotating

Experienced motorists are faced with situations when a spark appears, the starter rotates, but the lower part of the spark plugs is filled with gasoline. Do not be deluded by the presence of a fire, since this event can occur irregularly under pressure and can be lost while the engine is running.

The cause of the event appears to be excessive pressure in the cylinders. It will be possible to identify the event and the factors that motivate it by monitoring the car on a stand that simulates a combustion chamber.

We recommend paying attention to the valve timing, because their failure will be the cause of wet electrodes

. In injection internal combustion engines, motorists should check the functionality of the bypass valve located on the fuel rail. If its malfunctions are ruled out, you will need to find out the gasoline pressure in the rail, because the manufacturer regulates this parameter. Sharp fluctuations and going beyond the specified interval (larger/smaller sides) can block the start of the internal combustion engine or stimulate flooding of contacts for spark ignition.

Diagnostics will need to be carried out for the sensors of the electronic control system and for the injectors. An example of a failure is when the coolant temperature sensor sends incorrect data. In such a situation, the control unit unreasonably over-enriches the fuel mixture. Much less often, the culprit of incorrect impulses is a failed electronic control unit or a malfunction of its software. In this case, problems will appear not only with the ignition.

Features of starting a car in cold periods

In cold weather, before starting, you must first load the battery, then disconnect it for a while. After waiting a few minutes, you can try turning the starter to start the engine. If you fail to start the car on the first try, then in order not to fill the injector, you must wait a few more minutes. If all preventive measures were carried out in full before the frost, then there should be no problems with filling fuel.

We can list several conditions that are considered optimal for normal operation of the injector:

presence of a working starter;
maximum battery charge. The battery is powerful and in good condition;
seasonal lubricant is used;
spark plugs and high voltage electrical circuits must be in perfect condition;
clean, adjusted nozzles are installed;
The gas tank is filled with high-quality fuel.

There is an opinion among experienced drivers that driving a car along the highway at a speed of 120 km/h helps to self-clean car systems, including the fuel system. You can also run the engine at 5000 rpm for about 10 minutes in the morning. The effect is similar to racing on a track.

It is believed that when high pressure is created in the systems, self-cleaning occurs. These measures can only be carried out if the car is in good condition and a significant increase in pressure in the systems will not harm it.

What steps do you need to take to get started?

The question arises, what to do if the car is not old, all systems are in order, but in the cold it refuses to start? When turning the spark plugs out, it turns out that they are wet. As already mentioned, in the cold season, the cause of this phenomenon may be weak compression, low-quality fuel or a weak battery.

Let's look again at the manufacturer's instructions. The book on car operation defines the following algorithm of actions:

Turn out the spark plugs.
Wipe them thoroughly and dry them.
Run the starter for a few seconds.
Put everything in place.

Often, car owners clean the injector using various fuel additives. This is not recommended at all, firstly, the quality of the fuel mixture is lost, which negatively affects the operation of the entire piston group, and secondly, the injector should be cleaned using special equipment.

Experienced drivers carry several sets of spare spark plugs with them. The quality of the spark produced depends on the technical characteristics of this ignition component. There is no point in saving on candles, their cost is not that high, and low-quality candles can cause a lot of problems.

What you need to watch out for so that the spark plugs are not flooded with gasoline

To ensure that such a problem, when the injector fills the spark plugs with gasoline, does not arise in the future, it is necessary to ensure that the following conditions are met in the car:

battery is normal;
starter is ok;
normal oil should be poured in that can withstand frost;
The spark plugs and high voltage wires must be in order;
the injector nozzles are cleaned and adjusted correctly;
Only high-quality fuel is filled and only high-quality fuel is always filled.

And the most important thing to do with a car so that the spark plugs never flood with gasoline is to let the engine “sink,” that is, organize races several times a month and spin the engine up to 5000 rpm for 10 seconds. After such a load, all carbon deposits and other deposits in the combustion chamber will be blown into the pipe.

You can also go long distances and drive at high speed, for example, it is advisable to drive 100 km at a speed of 120 km/h, you can do more if it’s not scary. Then the engine will feel great.

If there is no need to travel that far, then just spin the engine to 5000 rpm a couple of times a month. And for those who every time abruptly leave a traffic light at high speeds, such a problem as filling the spark plugs with gasoline does not exist at all.

The following is a video about what to do if the candles are flooded with gasoline in the cold, what to do in this situation:

All car enthusiasts, sooner or later, encounter various malfunctions. Owners of VAZ 2109 cars, and other brands, are often faced with the problem of being unable to start the engine. Moreover, this can happen even if the day before the car started up perfectly and felt great on the road. Something happened during the night that prevented the engine from starting...

There can be many reasons for this behavior of the “iron horse”. However, most often the car simply fills the spark plugs with gasoline. This can happen both in a car with a carburetor and with an injector - the type of fuel system does not affect this misfortune at all.

It is interesting that the VAZ 2109 spark plugs most often fill in the winter season, that is, at sub-zero temperatures. And in this article we will try to figure out why this happens in general, and what to do?
