What to Do If the Idle Speed Is High After Cleaning the Throttle Body?

[StEvelyn]

After cleaning the car's throttle body, the high idle speed is caused by the removal of carbon deposits from the throttle assembly, which leads to an increased air intake compared to normal conditions. At this point, the throttle body needs to be reprogrammed via computer. If reprogramming is not performed, it may take a long period of driving before the idle speed returns to normal. Here is some relevant information about the throttle body: The throttle body is a controllable valve that regulates the amount of air entering the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, it is often referred to as the throat of the car engine.
