:mad: Well my idle is bouncin again, and the worst part is that my ECU is throwing a code 14, which is specified as an IACV problem. But I JUST replaced the IACV a couple months ago, and when I replaced that, the problem didnt immediately go away until I adjusted the idle screw. Does anyone have any idea what else could be wrong? Could there be something wrong with my throttle body? Any ideas would be appreciated.

I had the same problem, I replaced the iacv and the fast idle thermal valve. The idle problem stopped for a few day, but came back. There are two things it could be. First, you have a small hole in your intake manifold gasket, which will cause un-regulated air to enter your engine, which will throw the computer off. Or, there is a little white plasitc screw inside one of the sensors on the intake manifold, can remember whic one exactly. All I know is you need to take out the plastic white peice and clean it with a cloth so it looks new again. It will move back and forth move freely and should fix the idle. When it is dirty, it sticks to one position. Hope this helps you out.

if youre getting a code 14, then it IS the iacv. not something else. get ahold of a flow chart to diagnose that problem, if you cant, pm me. there might be an open in one of the wires that goes to the ecu (worst case scenario). i dont think its that, but check everything.
