Well i have had my Ca in for about 3 weeks now. I am starting to drive it more often, latley I have noticed the idle is very jumpy. Everthing will be fine when its cold, but as soon as the car warms up (temp gauge gets in the middle) the rpms go as low as 200 -300. Sometimes it will die especially if I am coming to a stop and push the clutch in it will die. I have tired to change the idle some on the intake manifold and does idle higher but still continues to drop. Does it have anything to do with a temp sensor or anything since it does it when its warm ? I bought a turbo timer, but see no use for it if the car will not stay running. By the way the car is running rich. Its just kinda sucks when you have to conitue to start the car when driving it around. Any help is appreciated thanks..

Do diagnostics on your ecu and see what kind of codes it might give you, a bad temp sensor can cause similar senarios. I doubt an O2 sensor can cause it but every thing is possible.What kind of MAF are you running and is the ecu stock or rechipped?

Run the self diagnostic on the ECU and let us know how it comes out.
