What is the reason why Fox can't lift the speed when stepping on the gas pedal?

The following are the reasons why Fox can't lift the speed when stepping on the gas pedal: 1. When stepping on the accelerator, the cable will drive the accelerator, that is, there is a position sensor on the accelerator. The control unit knows the throttle opening according to the signal of the throttle position sensor and calculates the corresponding signal voltage. According to the signal voltage, the fuel injection quantity of the vehicle is calculated. If the throttle position sensor is too dirty or the voltage is out of balance, the electronic throttle will fail and the throttle will not be pressed to the bottom. 2. The fault of electronic throttle has been eliminated. The throttle position sensor signals in the engine intake, oil circuit and ignition system need enough air to ensure the normal operation of the engine. If the air intake system leaks or blocks the valve of the car, the power will drop, the speed will not go up, and the car body will shake. 3. The oil system of the engine is very important. Adding inferior gasoline may lead to gasoline pump combustion, three-way catalytic failure, piston failure and other phenomena that directly affect the engine power, which may easily lead to engine flameout and acceleration.
