how to set the idle goes back to normal ?
After cleaning the throttle body,my car idle goes up to 1400rpm and check engine light comes on when i drive about 20 miles.Please give me some advise to set the idle back to normal,at 800rpm.Thank you.
You may have got some gunk in the idle air control when cleaning the throttle body. Get the codes checked, see if it is IAC related.
thank you tennisshoes.i will check it out
you're absolutely right.A lot of gunk came down from throttle body to IAC.It made the valve could not move freely and its sensor couldn't work properly. I realize that throttle body and IAC should be cleaned at the same time to avoid the dirt moves from one part to the other.,and make problem for the engine. Thanks again for your advise.
