Why does the engine speed increase after cleaning the throttle body?

[RubyLynn]

Once the sludge in the throttle body is removed, the ECU still controls the throttle opening based on its memory, which inevitably leads to an increase in the air intake corresponding to the current opening. Cleaning interval: It is generally recommended that owners clean the throttle body every 20,000 to 40,000 kilometers. However, this is only a reference value. The specific cleaning interval should be determined based on individual driving conditions, air environment, type of engine oil used, frequency of air filter replacement, and driving habits. Unstable idle speed: If you notice insufficient engine air intake, unstable idle speed, a sudden feeling of throttle release while driving, reduced power, or even difficulties in starting the engine and increased fuel consumption, it may also indicate that the throttle body needs cleaning.
