Wuling glory idle speed is unstable. What is the reason for the intermittent?

Idle instability is related to idle motor failure or idle metering hole blockage, and may also be caused by lack of cylinder. It is suggested to clean the throttle and idle motor, clean the nozzle, replace the gasoline filter and clean the filter screen of the fuel pump. Check the cylinder pressure and spark plug gap of each cylinder. Check whether the cylinder pipeline and high-voltage coil are normal. Check whether the intake pressure sensor is normal.

Idle motor is an element to control the idle speed of motor vehicles, which is mainly used to bear the idle speed of motor vehicles. Its purpose is to adjust the idle speed according to the engine load at idle speed. Idle stepper motor is installed on the throttle body and used by the engine controller to control the idle speed of the engine. When the engine speed deviates from the idle speed, it is adjusted by the throttle valve to control the amount of air entering the intake manifold, which is mechanically operated by the accelerator pedal wire rope. The throttle body has a bypass air passage to provide air when the engine is idling (when the throttle is closed).

When idling, the cross-sectional area of idle air passage is changed according to the temperature and load of the engine, so that the engine has the best idle speed under different working conditions.
