How is the idling instability after cleaning the throttle and nozzle of the car?

Because in normal use, when the throttle valve is slowly dirty, the opening will be slowly adjusted with the degree of dirty. The dirtier it is, the bigger it opens. To a certain extent, the phenomenon of unstable idling and flameout will occur. When you clean up dirty things, the throttle opening will keep the original opening, and the air intake will increase, resulting in excessive idle speed. Some cars drive slowly or idle for a long time, so they can adjust themselves. Many cars need to be matched.

Throttle is a controllable valve, which is used to control air to enter the engine. After entering the intake pipe, it is mixed with gasoline (different models of cars have different design mixing parts) to become combustible mixture, which participates in combustion and does work. Four-stroke gasoline engines are generally like this. Throttle is the most important component in EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.
