what other mods do you have done tot he car? and what did you clean it with? and how is your MAF sensor?? you could also check the gasket on the IAC to make sure it is still good, if not you might have a slight vacuum leak??

Did you ever figure out what was causing your idle troubles? I am having issues with my idle now. I just replaced the IAC to eliminate it from potential causes. I just had cams and long tubes installed and the tech doing my custom tune could not get the revs to stop hanging and also the car will sometimes choke off at idle. I am a little upset with how it runs right now. I did not have these issues until I took it in for the mods and tune. The cams are Hitech StageIIs and are not too radical. I don't think that is the root of my troubles here...

Any ideas???
