After cleaning the throttle, the idle speed is high.

Hello. This situation may be that the throttle valve is installed in an incorrect position, the seal is not tight, and air leaks. Or if you don't match the computer after cleaning, the idle speed will be high. I hope my answer can help you. Have a nice trip!
