Why does the car shake a little after cleaning the throttle and carbon deposit?

Throttle can not effectively determine the minimum airflow position, but can determine the maximum opening position. Therefore, if this happens, the throttle will step on the accelerator pedal several times at idle speed (that is, slam on the accelerator) and slowly determine the optimal opening at idle speed. The engine will slowly stabilize the speed and learn accurately in the later driving.

The throttle opening of a car controls the air intake. There is an air flow sensor in the air intake pipe of the car, which will control the fuel injection quantity by computer according to the air intake. This change can be detected by the air flow sensor, and the fuel injection quantity of the engine can be controlled according to the detected value to achieve the best combustion efficiency.

Precautions:

Because several cars use electronic throttle, the electronic throttle is more accurate in the control process. Once the power is cut off, the electronic throttle will lose its matching value. If there is no matching value, the electronic throttle will self-learn, but the speed of self-learning is related to the control logic and the type of control sensor.

The purchased cleaning agent is very corrosive, and it is easy to cause excessive corrosion of aprons or oil seals during cleaning, resulting in unstable idle speed. Excessive cleaning of the throttle will also lead to premature scrapping of the throttle, and the throttle will not be broken because of dirt.

Throttle is the mouthpiece for the normal operation of the whole automobile engine. 4S shop suggests cleaning the car when driving to about 20,000 kilometers. Of course, this kilometer number is not very fixed. According to different models, some models can be eight or nine thousand kilometers.
