car wont hold idle
The car starts and runs for a few seconds then the rpms drop down and the car dies. if you hold the throttle around 1500 it will stay running. As soon as you let off the throttle the car dies. It is a 88 s4 na, completely stock. Any ideas on what could be wrong?
thanks

Sounds like a big vacuum leak and they can be tough to pin down. Check all the obvious places like the vacuum hoses for tight fits at each end and no cracks. Then the gaskets between UIM and TB and the UIM to LIM. You can also develop vacuum leaks at the fuel injectors. Fix the vacuum leak and your problem should go away.

It really sounds like a vac leak, but if you're sure it's not then the next thing to do is verify the setting and function of the TPS. And make sure your idle speed is correctly set.

You need to adjust ur throttle.. I been having the same problem off and on but each time i make a small adjustment on the screw on the side of the throttle it gets better and i havent stalled yet on a cold start for about a day now... yesturday i was stalling a lot till i made that small adjustment in the throttle... check out my other thread rotaryrocket member has posted a link in my other thread on how to make the adjustments... thats what u need to do like i have to....
