Noticed the car would idle a bit low then come back up to regular idle. Hoses are ridiculously hidden. I unbolted the IAC and with teh hose attached just sprayed some Carb cleaner thru the Screened hole (intake side) and the other hole ( output side). It made it worse. Has anyone had success taking it off and pulling that bottom plate and cleaning it better? I have always cleaned these on my other cars without issue. What the heck is the Idle Intake Thermo Valve? has anyone needed to clean that?
