The fuel filler door of the car feels cut off.

There are many reasons for this phenomenon, which may be the problems of oil supply system, ignition system or air intake system.

At present, all cars use electronic throttles. When you step on the accelerator pedal, the throttle opening will increase and more air will enter the engine. As the amount of air entering the engine increases, the fuel injection will also increase, thus increasing the engine speed and accelerating the car.

If there is something wrong with the accelerator, the accelerator opening will not increase after stepping on the accelerator pedal, which will cause boredom and fuel cut-off during acceleration.

The normal operation of automobile engine is inseparable from the fuel supply system. If there is something wrong with the gasoline pump or injector, it can't be injected when more fuel is needed, and the car can't accelerate after stepping on the accelerator.
