my car is slowly turning into a paper weight...
ok so first I had a coolant or oil problem. Then a boost problem.... Now my car idles really weird. On my way to work, as I came to a stop, by car's rpms would drop really low then stall the car, I couldn't get my car started for 5 min. Then the whole way to work I had to put it in neutral and rev it a little so it didn't die on me.... WTF is going on!!!!!!

If I remember right, you mentioned in a different post that you have VagCom - at least for the time being, until the problems are sorted, use that to bump your idle up a bit. With my car, after a battery disconnect, it takes my computer several days to fully relearn itself and during that time it'll stall sometimes when coming to a stop or if I have to put the clutch in quickly (causing a quick drop in RPM). This is the case even though I do a throttle-body realignment first thing when the battery is hooked back up. Last time I had to deal with this, I met up with Hiwords and he upped my idle speed by 100RPM and I didn't have any more trouble with stalling. It's at least a temporary idea to try while you sort things out and it should help keep your car from infuriating you to the point of running it off a dock into a lagoon.

It's definitely worth a shot. My revs would still dip somewhat, but maybe only down to 500 or so before the engine would catch itself, and come back up to where it should be. From the moment we did that, I didn't stall out again. Hope it works for ya.

yea its a 99.5 says in sig.. im gona try the vag-com idle crap first then ill check the icm. im using the stock airbox so the ICM is still mounted on the top using the original heatsync so it should be good.

Do not mess with your idle with vag com. You are only covering up a problem by doing that. I didn't read any of the other replies, but it sounds like you have a vac leak.
