How to solve the problem of low idle speed of Li Xia N5?

The idle speed of the car is more than before, which is caused by the dirty throttle everywhere. Just wipe the throttle clean.

When adjusting the idle speed, the speed should not be high and low, otherwise it will cause early wear and tear to the engine, so it is best to adjust it in the automobile maintenance department.

As long as the idle speed is kept between 650 and 850, the automobile engine can work normally and the fuel consumption will be reduced.

When idling or stopping at low speed, it is easy to turn off the fire (waiting for traffic lights, it is common to slow down when turning). Influence of low idle speed on gear shifting.

Precautions:

1. When the idle load of the engine increases, the ecu controls the idle control valve to increase the air intake, thereby increasing the idle speed and preventing the engine from being unstable or flameout. When the engine idle load decreases, ecu controls the idle control valve to reduce the intake air, thus reducing the idle speed and avoiding excessive idle speed.

2. When the working parameters of the engine deviate from the normal value, use the idle speed control valve to adjust the idle speed. Idle speed is regulated by controlling the amount of air bypassing the throttle body. After the engine is started, the idle control valve is opened for a period of time, and the air intake increases, which increases the idle speed of the engine by about 150r/min-300r/min.

3. When the engine coolant temperature is low, the idle speed control valve is opened to obtain a suitable fast idle speed. The engine computer controls the position of the plunger of the idle control valve by changing the signal intensity sent to the idle control valve according to different coolant temperatures.
