What is the jitter at idle speed after cleaning the throttle?

It may be: engine computer adaptation. After the throttle valve is cleaned, the carbon deposit on the bypass valve is gone, and the computer can't adapt to it for a while, so it can be matched by idling for 4 s.

It may be that there is too much carbon deposit near the injector, the spray atomization effect is not good and the oil supply is insufficient, which leads to this phenomenon. It is recommended to clean the injector, which is also related to the quality and oil number of the oil used. Now it is necessary to use a diagnostic instrument to detect whether there are problems with related sensors, throttle position sensors and oxygen sensors. If the jitter is serious, it may be that the idle speed is unstable and needs to be adjusted. Generally, the idle speed is around 800- 1000.

Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine.
