Chevy Tracker Low Idle

Hi All,

A friend of mine has a 2002 Chevy Tracker with a 2.0 Manual trans. He recently started having low idle problems. Checked for codes ans had one (low RPM code). Removed the IAC to see if there was any carbon build up but there was noe. I dont know what to check from here. Any ideas? Note: the vehicel runs great other than a very very low idle.

OK,

I just took it to Autozone and had them run the codes again due to the engine light being on steady. Now it is running a Idle speed circuit code which from what I gather could be the IAC sensor or the Throttle position sensor. How can I check which one is bad?
