Geely Jingang throttle gasket

The engine has serious carbon deposition.

It may be that there are carbon deposits in the throttle, spark plug and inner wall of combustion chamber of the car, depending on the situation.

1, the idle speed of the car is relatively low (below 800-850 rpm), but after turning on the headlights, the idle speed of the engine will drop even lower, and your idle speed cannot be adjusted automatically (it is estimated that it is not an EFI car), so the engine is shaking badly, which is the greatest possibility. There is something wrong with the automobile power generation system. The voltage used for power generation is not enough, which leads to the unstable operation of the ignition system and the car shaking. It is recommended to check the engine idle speed, which is not lower than the normal value. If it is too low, it will also cause engine wear. (Low lubricating oil pressure) After starting the car, check that the generator voltage is kept at 2000rpm5 for 5 minutes, then turn on all the electrical appliances on the car and measure the battery voltage. If it is higher than 13.8v, it is normal to be lower than 13V, that is, it will not generate electricity.
