The engine of Changan Automobile S460 is shaking and the idle speed is unstable!
1. Air leakage in the intake manifold: When the air, gasoline vapor and combustion exhaust gas that should not enter the intake manifold are too rich or too thin, the idle speed of the automobile is unstable.
Solution: Check the manifold and replace it in time if there is air leakage.
2. Too much carbon deposit on the throttle: too much carbon deposit on the throttle and the surrounding air intake, and the cross-sectional area of the air passage changes, which makes the control unit (check the transaction price | participate in the preferential policies) unable to accurately control the idle intake, and also causes the mixture to be too rich or too thin, which leads to the unstable idle speed of the car.
Solutions;
The best way is to clean the oil circuit, clean it regularly and use fuel additives such as PNF stock solution to solve the above problems caused by carbon deposition. The poor quality of fuel or the long storage time of fuel in the initial stage of a new car will lead to the rapid increase of colloidal components in the oil circuit, which will continuously pollute the fresh fuel, resulting in no good fuel to participate in the combustion in the later stage, and the carbon deposition exceeds the standard, especially for the national six cars. Only by maintaining a clean oil circuit can most problems be gradually alleviated.
