Is it normal for the sound to get louder after cleaning the throttle?

Hello, dear! Are there no matches after clearing the throttle? I suggest you go back and let the maintenance master match it again.

At present, most models need to be re-matched after cleaning, so that the engine computer can identify or adapt to the cleaned throttle more quickly, thus effectively controlling air intake and fuel injection.

Or wait for a while, because ECU has self-learning function, it may take a long time.

Suggestion: match it after cleaning, thank you.
