BoostedCobra

When I start my car, if I don't gas it, it dies. If I leave it runing by itself it dies. If I turn at a slower speed (like 15 or so) while the clutch is pushed in or the car is in neutral, it dies. Somebody said that it might be bad O2 sensors. I have no clue. Any ideas?

is it throwing any codes?

No, and the check engince (or any other light) isn't on either. Some people said it is the Idle Air Control. The car was just tuned up and it is running perfect, except for the idling part.

if the idle air control valve was bad, it should throw a code. have you checked for vacuum leaks?
