Stalls at Idle (AODE)

[SteedaGT9150]

not my car, but my girlfriends fox will stall at idle, well pretty much run like crap at idle. under acceleration it drives fine, but at idle its just rough and usually dies. i just changed the plugs which helped, but its still doing it. the car has some kind of cam in it, unknown to me her dad rebuilt the engine but they dont talk so i have no idea what it is. any ideas guys?

edit - 91lx still has the 302 in it

FYI, just AOD, not AODE. Check your timing and clean the MAF for starters, see where you're at after that.

Pull codes.

Has the IAC been touched, cleaned or replaced lately?

See the "Surging Idle Checklist for help with all your idle/stall problems. Everything you need to find and fix idle problems is in there.

The first two posts contain all the updates to the fixes. At last count there were 24 possible causes and fixes for surging idle/stall problems. I continue to update it as more people post fixes or ask questions.

Have you checked the O2 sensors and the wires leading up to them?

I was just thinking...why do you say it "def has a cam"?? Does it sound super lopey and mean as hell? Might want to start checking all your vacuum lines under the hood. As far as the IAC is concerned, just pull it off and clean it with throttle body or carb cleaner, there's two holes in it, clean out both.

ive been around my share of stock and modded fox bodies, owning one for 4 years, and its def got a cam. when it does run right at idle it lopes, my buddy owns a well known performance shop around the area and also mentioned something about it.

and ill have to check the 02 censor.
