Is high idle speed normal after cleaning throttle and idle valve?

Refreshing the computer should basically return to normal after running for a period of time. Don't listen to some unscrupulous vendors outside saying how often to wash or something. Open your mouth and say the throttle needs washing. Actually, there is no need to wash that thing often. Unless it's really dirty, it's best to clean it. Generally, it is not necessary. Less demolition. In many cases, the vehicle problem has nothing to do with the throttle.
