What is the reason why the car is not idle?

Maybe the throttle is broken, or the idle speed control valve is broken. The rider is advised to replace the damaged parts.

All automobile engines use electronic throttle valve, which is called the throat of automobile engine.

Throttle can control the amount of air entering the engine. When we step on the accelerator pedal, we don't directly control the fuel injection quantity, but the accelerator pedal controls the accelerator opening.

When stepping on the accelerator pedal, the throttle opening becomes larger, and the amount of air entering the engine becomes larger, so the fuel injection will also increase.

The classic car will use the cable accelerator and connect the accelerator pedal with the steel wire. There is no physical connection between the accelerator pedal and the throttle of the electronic throttle engine.

If the car is not idling, it may be that the accelerator is broken, or the idling motor is broken, so riders need to check which part is wrong.

When the car is idling, the idling motor on the throttle controls the air flow into the engine. If the motor is damaged, it will lead to engine idling or unstable idling.

Long-term use of throttle valve is easy to produce carbon deposition. It is recommended to clean the throttle carbon deposit regularly.
