my car dies at idle now. I can't keep it running long enough to put it in gear. I searched around and found I guess I need to check the IAC which is on the throttle body? I'm looking but I can't find anything that shows where the throttle body might be located. Hint?

thanks. I found a page with with a written description of where it is.

since i have the thread open, I've noticed that when the engine sits and gets cold, it idles high, but the more it warms, the lower the idle RPMs drop until the engine dies. Is this what I should be checking?

maybe your idle speed is set too low...
maybe its your ignition system...
maybe you have some vacuum leaks...
maybe its your fuel inection system...
maybe you EGR valve is not closed...
or even your compression is too low...
maybe your PCV valve is fucked...
maybe your PCS is fucked...
it could be a lot of things
check your hoses make sure they're all atached and not cracked or something.

just my opinion someone correct me if im wrong.


does it have a rough idle when it does start?

No mods, and it only idles rough when the engine heats up.

found the throttle body, but I have no idea where the idle adjustment screw is at. Heard it was under some rubber thing, but couldn't find that either

i have no idea how to check those things you listed anyway. goddamn car

here try this turn on the ac when it idles rough...if it get better it definetly cuz of your idle screw.

turning on ac boosts the idle speed...

if so you rpoly have to adjust the screw or replace it if its worn out
so try this...

oh and the screw is on top and a lil to the back on the throttle body

ps if you adjust the screw and the problem comes back you have to replace it.(dont worry its cheap)

marius is on the money.

if engine speed increases with A/C on and when you turn the steering wheel, your IAC is probably fine. (I am convinced that a lot of good IAC's have been replaced unnecessarily. IAC and O2 sensors have been blamed incorrectly for everything ranging from rough idle to the AIDS epedemic.)

Exact same symptom 6 months ago on mine. The idle screws on these cars seem to self tighten. At a minimum, you should replace the o ring on the idle screw. Also common that the rubber grommet is missing because when the o ring gets old, it allows boost gasses to flow by and push out the grommet.
