I was driving along today, when I came to a stop and my engine died. Ever since, it idles at around 400 - 500 RPM and conks out after a few seconds. I do have an exhaust leak in my downpipe, but could this be a cause for my car not idling? tomorrow i'll check antifreeze and look for a vacuum line detached, but i figured i'd bring it to the pros quick.. anyone else have any ideas?

thank you!!

Do a boost leak test??

your leak in your downpipe SHOULD not be the problem.. most likely a vac hose popped off from somewhere i have had it happen before.

there are ALOT of hoses by the intake mani make sure you looked over them good.

is there an easy way to do a boost leak test without equipment?

thanks vvhiteix, i'll look it over better, i didn't have a flashlight at the time.

i talked to a friend of mine who is a mechanic and he's guessing the throttle body is just gunked up. he also said most vacuum leaks will make the car idle higher. i checked as many hoses as i could see, i didn't see anything that looked off.

anyone know how to do the boost leak test?

idle control valve. theres also an idle adjuster screw on the throttle body try that. no codes?

no, no codes, i'll look for the screw on the throttle body tonight (though this sounds like masking the problem instead of fixing it), i heard it might be under a rubber cap or something.

Have u checked all the connections from the intake manifold to the fmic? It sounds like maybe a coupling is disconnected. Check the ones on the fmic, also.

ok, so i turned that phillips screw on the backside of the throttle body.. out about 3 turns and the idle went back up to 900 RPM. i'm sure that's just masking the problem, plus this morning when i started my car it wouldn't stay running until it was warm. at least once it's warm it stays running at stops now.

i think the problem is either..
boost leak or gunky throttle body. i'm hopefully having my throttle body cleaned this week.
