Excuse me, what is the reason why the fuel door engine will stall after ignition?

1. The throttle valve is dirty with dust.

In this case, when the car accelerates, the throttle opening will be reduced or stuck, and even the engine will stall. At this time, it is necessary to clean or replace the throttle to match the throttle.

2. The ignition coil is damaged and the coil is open or short-circuited.

When it is difficult to make an accurate judgment through visual inspection and resistance measurement, a new ignition coil should be used for comparative test to check the ignition coil.

3. Steam;

The oil filter element is too dirty.

When the vehicle accelerates, the oil circuit will be blocked. In this case, the problem of flameout during acceleration can be solved by replacing the gasoline filter element.

4. The air flow meter is damaged

Replace the air flow meter.

5. The gasoline pump is not good.

When the car is running, the oil pump can't keep the oil pressure or the fuel injection quantity is insufficient, which leads to the flameout when accelerating. In this case, if necessary, replace the gasoline pump and clean the fuel tank. Check throttle and fuel injectors.

Prevent flameout

The flameout is a common problem for beginners to drive. I believe that many people have encountered such a situation, starting the flameout when the red light turns green, starting the flameout when following the car, not shifting gears in time, stalling when the braking range is too large, and stalling when the steering angle is too large.

Although there are various situations of flameout, it is mainly caused by improper matching of clutch, accelerator, brake and gear, which requires novices to be familiar with the vehicle they are driving as soon as possible, master the weight of accelerator pedal and the length of clutch free stroke, and make adjustments if the pedal position is not suitable.
