After cleaning the throttle, the throttle is too high, just like stepping on the throttle to the end. Did you break the idling motor when cleaning?

If cleaning is removed, pay attention to whether the cleaning agent is sprayed into the gap of the idling motor, remove the idling motor, check whether there is liquid on the copper contact pin of the potentiometer and dry it. Connect the diagnostic computer, reset the throttle, and then try idling. Generally, the EFI car needs to do computer reset after cleaning the throttle.
