What happened to Qi Jun 2.5 without throttle?

Hello, if there is no response when stepping on the accelerator, first check whether his electronic accelerator is controlled by the accelerator pedal. If it is out of control, it is necessary to check whether the position signals of the electronic throttle and accelerator pedal are normal and whether the throttle actuator motor is faulty. If the throttle is normal, it should be caused by abnormal fuel injection. It is necessary to check whether the pressure of the gasoline pump is normal, whether the gasoline filter element is blocked and whether the signal of the air intake sensor is normal. If there is any problem, please repair it. I'm happy to answer your question. I hope I can help you. Have a car.
