Clean your IAC (Idle Air Control) valve. It's a little square inlet inside your throttle body, facing towards the front. It gets clogged by oil and gas vapors from the PCV system, and gets stuck every now and then, causing an irratic idle.
can someone take a picture of the IAC, just to have a better idea of what i will see, also do i used the same stuff that we use to clean the maf, to clean the IAC??
The actual IAC housing is bolted to the bottom of the throttle body. The inlet to it is inside the throttle body, on the bottom half facing the front, right before the throttle plate. It's a square shaped hole. Just spray a ton of throttle body cleaner into it and let it sit for a few min, then start up the car and let it idle for a while to flush out all the gunk.
