What happened to the unstable idle speed of Peugeot 5008 after clearing the throttle?

Reasons for unstable idle speed of throttle valve after cleaning Peugeot 5008: 1, air, gasoline vapor and combustion exhaust gas that should not enter the air manifold, resulting in too rich or too lean mixture; 2. Too much carbon is deposited in the air inlet around the throttle valve, and the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake, and also causes the mixture to be too rich or too thin.

Because the throttle opening has not been reset. Due to the long-term carbon deposition on the throttle, the carbon deposition squeezes the throttle, and the throttle opening also expands. After cleaning the throttle, if it is not reset, the throttle opening will remain in the state before carbon deposition, which will lead to an increase in air intake, and in severe cases, the idling will be unstable.

Causes of unstable idle speed after cleaning throttle;

1, too much carbon deposit If the carbon deposit in the engine cylinder is serious, it will cause spark plug blockage and valve blockage, which will directly affect the shivering and vibration of the car at idle speed. If the acceleration ability of the car is not as good as before and the vibration is lasting, then you can consider cleaning the engine cylinder;

2. Failure of the oil supply system. Unstable oil pressure will easily lead to unstable mixture concentration, which will not only cause trembling and vibration, but also cause unstable idle speed.

3. The first task is to consider replacing the gasoline filter. After all, the filter element may be blocked if used for a long time. If the oil pressure does not pass through the gasoline filter, there may be something wrong with the oil pump.
