Ok - All of a sudden my 97 E39 (AT) will not idle. It will start just fine - but if I don't keep the accelerator slightly down it will not keep running. I can even put it in gear and drive - but it takes a two footed symphony to keep the engine running without braking too hard and too fast - lot's of "FUN" (had to get it home from work!). Any suggestions?
Also - my drivetrain I think is really screwed - please check out my other posting from week or so ago and give me some suggestions - it would be very helpful and very much appreciated. Thanks!
You're looking at a vaccum leak by the way you describe it. I guarantee it. It's not going to be any thing to do with your IAC(idle air control) valve. If it was, you'd have a surging symptom because DME would try to compensate for the lack, or the excessive amount of air. Go to autozone or wherever sells carburator cleaner. Get a buddy to crank and keep the car running. Spray the carb cleaner all over your vaccum hoses. When your idle rises, check the hose where you just sprayed. You'll probably see a broken hose or a missing hose or in most cases a crankcase ventvalve is cracked.
