How long can it take to clean the throttle and idle for a few days?

After cleaning the throttle, the idle speed will generally return to normal after 1 to 2 days.

First, under normal circumstances, after the electronic throttle has been cleaned, it is best to use a computer to re-match and reset the throttle, so that the idle speed of the vehicle will not be too high.

Second, if there is no match, this is usually open for 1 to 2 days. Slowly, the vehicle driving computer will return to normal after adaptation.

Third, if the idle speed is always high, then this situation can be handled temporarily and the battery line can be broken. If the negative electrode really doesn't work, you can only go to the nearest repair shop and re-match it with a computer.
