Could you clean the throttle yourself, please?

Idle speed is unstable or about 30 thousand kilometers for cleaning. There are two ways to clean the throttle: one is not to disassemble or wash it. One is to remove it and clean it. Actually, it's about the same. The key is to look at the operation of the maintenance technician. Reminder: Because the computer has the memory function, it has adapted to the state of the throttle before cleaning, and the throttle opening changes directly after cleaning (even if it is small).
