What will happen if the accelerator of Changan second-generation van is faulty?

When the accelerator of Chang 'an second-generation van is faulty, there will be unstable idle speed, difficult starting, insufficient power and reduced ride comfort. The engine uses an electronic throttle, which is called the throat of an automobile engine. Throttle can control the amount of air entering the engine. After stepping on the accelerator pedal, the fuel injection quantity is not directly controlled, but the throttle opening is controlled. When the throttle opening becomes larger, the air quantity entering the engine will increase and the fuel injection quantity will also increase.
