alright i searched....but all i could find was normal idle speeds......which mine is not. i run aroudn 1100-1200 idle on a recently rebuilt motor. any ideas what my problem is? have downpipe, gutted cat, and radiator.

 

Has that beeen since rebuild ??? take car back to whoever rebuilt it. Sounds like you probably got a leak on the inlet manifold. lift bonnet up rev the engine from the throttle body and put your ear to the manifold and see if you can hear the sound of air escaping from tha region..

Spray some carb cleaner around the manifolds and see if your idle changes. If not, you probably don't have a leak. Try the air bleed screw or the idle screw on top of the tb.

 

well, if i put it in gear....it drops down to normal RPM...just when its in neutral. is this common for it to drop when in gear?

 

what ecu are you running?
