My car is stumbling at idle and I want to see if it's the IAC sensor. I'm going to clean it tomorrow with electronics cleaner and see if it helps, if not I would like to know a way to determine if the IAC sensor is bad.

Should get a code.

Go buy another one, put it in, if it helps great....if not, take it back and get a refund.

Probably a failing 02 sensor though. You might or might not get acode for that though, until it really gets bad or completely fails.

I have some spare O2's. I'll swap them out and see what happens.
