Yeah I have a intake manifold and throttle body coming in and I'm getting the IAC off of that. If that doesn't fix it then I might just give the idle screw a try. What bugs me is that sometimes, well very rarely it will idle fine in traffic normally after 30 minutes of driving.
Another thing I noticed was if I apply the brakes while idling it effects the idle along with me turning the wheel. If I'm at a light and I make almost a full rotation of the wheel while stopping, idle returns normal for 30 seconds and down it goes again.
Very interesting symptoms, but hopefully this IAC solenoid will do the trick.
