Hi, Does anyone know where the idle adjustment on the 03 Camry 4Cyl? I know where it is on my 99, but cannot find it on the 04.

The 2004 has an idle air control motor at the bottom of the intake throttle butterfly housing. The idle speed is not adjustable so don't turn the throttle butterfly stop screw. The Idle Air Control Motor (IAC) frequently fouls up with carbon. Toyota say replace the IAC, I take apart the valve and clean the throttle housing and IAC motor and have 95% success rate in cleaning them.
From my understanding the 2004 camry 4 cyl. IAC is attached to the throttle body and cannot be separated, how do you take it apart and clean the IAC?
