Yet ANOTHER Idle Problem..HELP!

[Krmnnghia]

OK so the car will not stay Idling for more than about 10 seconds before it dies. In those ten seconds it is very irratic...Going from 0 to 1K and stumbling. I have looked at most of the vacuum hoses and all are still on and tight, checked the entire intake and no leaks or loose clamps, Have not checked IC pipes but the car runs great when not idling so I don't think that would be the issue. The RPM's basically drop off when you put the clutch in. I have reset the ECU twice and let it sit and idle for about 10 minutes and it is fine...as soon as I take off and stop oh say 50 feet in front of me it idles low and will die. Anything else I could try? Thanks Guys!

The ISC motor (on the TB) could be gummed up. Hose it out with carb cleaner and a q-tip.

BTW.. do you have any clutch engagement issues (esp during left turns) or ticking sounds eminating from the lower part of the engine? If so check here: http://members.shaw.ca/costall/1000Q/answers-terms.htm#whatiscrankwalk

SWEET ok I will check it out...Do I need to take it off the TB and clean it up?

have you messed with your radio or any of the wires behind it?

Now that you mention it...My car was broken into and the CD Player was jacked...1 day later my Interior lights and Cruise went out and the idle is F'd up. Ideas?

UPDATE!!!

OK so this morning I spent a good hour taking all the IC pipes out and replacing them making sure everything was nice and tight and no hoses had any leaks... I also checked for shaft play which the tired t-25 has a little of

I found the dejon pipe connecting to the lower turbo outlet was a little loose so I tightened that one up and everything was fine. I made sure the MAF plug was in tight and all vacuum hoses were on and tight. So I started her up and she idled perfect...let it sit for 15 minutes and it went up and down till it settled at a perfect idle. Without shutting it off and reved it a few times and it was fine...took it for a 10 min ride and stopped 5 times at stop signs and let it idle...still perfect. Brought it back home and went through all gears and full boost and parked it for 30 seconds and still perfect idle. Shut it off, start it back up and its crap again! Idle bouncing all over the place and finally dying. WTF! Any ideas?

Sunday I plan on taking the TB off and making sure everything is cool with it. I ahould order a BLISS screw I think just incase. Any more ideas?

Ok so I was unable to get the ISC off as I was impatient and tired so I decided to play with the BISS screw and the idle screw. I took the idle screw out and moved it a little and also moved the Biss screw clockwise about a 1/4 of the way around. Car Idles perfect now. WTF? Anyone know why this would work?

heres one way to check to see if the ics works....... simply (if they work) turn your fans on or listen for when they come on, and if the idle lowers than the ics should be fine. b/c thats what its automatically supposed to do.

I changed my radio in my car and now it also Ildes bad. I just figured it was running bad. So did I mess with somthing while I was in there change out the radio??

OK GET THIS! When my Idle was all F'd up my ABS Light was on. Now that the Idle was fixed by adjusting the BISS screw and the Idle Screw the light is OFF! Damn these DSM's just screw with your head! Any ideas on that?
