iac valves
Just wondering what the difference in them is whether you have an engine oil cooler or not. I'm pretty sure mine is bad- engine idles at about 1000 but if I reset the IAC as on shbox's website it will idle down properly for a little bit then come back up after I drive it. IAC is a bwd from advance. They didn't ask me when I bought it last year if my car had an engine oil cooler or not. I ran the # and it's for one with an oil cooler- mine doesn't have one. It was fine for a year though. Just ordered another one for no oil cooler so hopefully that fixes it.

Yep I checked all the vacuum lines but I replaced all of them a year or 2 ago. I searched to see if I could find what the difference was between the 2 IAC's (besides the price) but couldn't really find anything definite. I can't imagine what the oil cooler would have to do with the IAC...

Just a few things to the engine but nothing internal that I know of. !egr, !air, Hooker LT's and 3" ORY, CAI. Mail order tune from Madtuner. When I started engine cold it was showing 0% at idle in open loop. Was idling around 900-950. When it went into closed loop idle went to about 1000-1050. Throttle angle was 0-1%. IAC counts @ 34. Idle speed is set to 800.

And the one without an oil cooler is more $. Well that fixed it for a few days. Now it's doing the same thing again. Now throttle angle is usually showing 3-6% at idle. If I reset the IAC it will be fine for a while- between 5 minutes and the rest of the day. TPS sensor maybe?
