Why does my car keep stalling? What s the deal with the car that keeps stalling?

1. Use low-quality fuel. Once the automatic car stalls, the main reason is the use of inferior (not up to standard) fuel, which in turn causes the engine to depot and stall.

2. Engine computer failure. From the point of view of kilometers, after using the car for a long time, the possibility of engine computer failure will be relatively large, once the engine computer fails, it will cause the car to stall, which is a problem of control. Just like the human brain, when there is a malfunction, the body "goes out".

3. The driving skills are not proficient enough. The driver's unskilled driving skills and improper operation will also cause the car to stall.

4. Multiple cylinder failures at the same time. It is possible that due to the failure of the spark plug or the high-pressure bag, one or more cylinders will not ignite, resulting in a flameout. However, only the failure of multiple cylinders at the same time and non-ignition can cause flameout, so there is such a possibility, but the probability is not large.

5. The engine itself fails. Damage to the engine idle motor or the wiring of the idle motor, or a problem with the idle control module in the engine's electronic control unit (ECU). The possibility of the engine itself failing is extremely high among the many reasons why a car stalls.

6. Oil pump failure. The stuck oil pump or the failure of the oil pump itself will cause a sudden lack of oil supply, and no oil supply will easily cause the car to stall.

There are two reasons for turning off the engine, one is to start the ignition, one is to turn off the ignition, the starting ignition is still too fast, step on the clutch to hang up to the first gear, slowly lift the clutch, when the clutch is in a semi-linkage state, the front of the car shakes, at this time put down the handbrake, the left foot must be stable and don't move, wait for the car to go for a second or two and then slowly lift all the clutch, refuel and shift. As for the halfway off, most of them are that you are obviously hanging in third gear, and if you want to stop, you will step on the brakes, and the speed does not match the gear, the correct way is to step on the clutch and then step on the brakes, and wait for the car to stop and pull the handbrake back to neutral.

Generally, automatic transmission cars will not turn off, most of them are manual transmission cars are easy to turn off, vehicles often turn off at normal times, this is a very abnormal phenomenon, if the fire is suddenly extinguished in the process of driving, it is very dangerous to think about it, usually this situation occurs mainly in the following situations, the first is the possibility of spark plug damage, because whether it is to start the start or in the normal engine work is inseparable from the role of the spark plug, her role in the engine can be said to be very important, The spark plug ignites the fuel mixture before the cylinder block moves, and if this part is damaged, it means that the engine loses power and can easily stall.

The main reason for the total stalling of the car is the use of low-quality fuel, which causes the engine to stall due to carbon deposit. Here's how to prevent your car from always stalling:1

Go to a regular, larger, and qualified gas station to refuel. 2.Refueling according to the compression ratio of the engine or the requirements of the car instruction manual is more scientific and economical, and can give full play to the efficiency of the engine.

3.Regular maintenance, often check whether the oil circuit and circuit are unblocked. 4.

The higher the fuel grade, the slower the oil burns, the lower the combustion knock, and the higher the compression ratio is required for the engine; On the contrary, the combustion speed of low-grade fuel is faster, the combustion knock is large, and the engine compression is relatively low.

It is necessary to check the possibility of damage to the Zhengji spark plug, because whether it is started or when the normal stool engine is working, it is inseparable from the role of the spark plug. It is also possible that the fuel supply is insufficient, and if the fuel is not enough, it is very likely that the engine will not be able to carry it, resulting in stalling.

1. If the ignition occurs during idling, the speed of the vehicle will not be very fast in the idle state, and it only needs to be ignited again after the ignition is turned off. If it is a car with automatic transmission, you must first put the gear into Zaocongtan parking gear (P gear) or neutral gear (N gear) before restarting the engine.

2. Turn off the ignition when coasting, first stabilize the direction, and at the same time slightly brake, at this time, the manual transmission model can step on the clutch, hang into the corresponding gear, and then release the clutch to bring up the engine by the speed; Automatic models need to be engaged in neutral (n) and then restart the engine.

3. If the manual transmission car has stalled, under the premise of quickly improving their driving skills, they must first judge whether the oil circuit is smooth, often due to this simple reason, the result is a waste of time. Completely dredge the oil circuit, including the fuel injection cavity slip adjustment, throttle and fuel tank, etc., it may be that the quality of the engine oil you add is not passed, and the oil channel is blocked due to too much grease.

4. At the same time, the possible reason for the flameout is too much dirt in the valve. When the engine is running, a lot of dust accumulates at the valve core and throttle seat of the motor, and when too much dust accumulates, the engine will have too low idle speed, poor idle stability, and finally cause idle stalling. At this time, you only need to swing the idle motor.

At the same time, the use of high-quality and decent fuel that meets the standards is also the key to solving the problem of car stalling and avoiding excessive carbon deposition in the cylinder. (Photo by Yang Weilin) @2019

The total stalling of the vehicle may be due to a problem with any part of the intake system, fuel system, and ignition system, resulting in the total stalling of the vehicle. Ignition is mostly seen in manual transmission models, and generally automatic transmission models do not turn off easily.

The oil circuit failure is generally due to the unqualified oil used, resulting in the oil circuit is not smooth, the gasoline pump is damaged, the vaporizer oil inlet is blocked, and so on.

Device failure may be due to a problem with components such as capacitors, ignition coils, spark plugs, and electronic ignition modules.

Possible causes of the air intake system: the air filter box, air intake pipe, crankshaft ventilation valve pipe, and crankshaft air inlet pipe fall off. In this case, only parts can be replaced.

It could also be that there is a problem with the throttle. For example, the throttle is blocked, the throttle has carbon deposits, the throttle opening is abnormal, and so on. If it is a problem with the throttle, the solution is to clean the throttle.

If it is a manual transmission model, the total stalling is likely to be caused by improper operation. Generally, because the clutch control is not good, the left foot lifts the clutch violently, or the right foot does not keep up with the throttle.

The correct operation is to lift the clutch with the left foot slowly, and when it is not fully lifted, the right foot can gently step on the accelerator and give a little oil.

When lifting the clutch, there is a linkage point, find this linkage point, and keep up with the throttle with the right foot.
