The idling speed of Wuling 465 engine is unstable, it will stall and change the throttle. What happened?

Hello, when the engine idling is unstable, the speed indicator on the instrument will jump up and down, and it is easy to turn off the engine. The throttle does not need to be replaced. Just clean it with chemicals. Mainly the motor idling. You can take it off the accelerator and see if it is dirty or broken. If it is dirty, install it by chemical cleaning. If you try it in the car, it will turn off. No, I suggest you get a new one. I hope I can help you. If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
