How do you know for sure that the IAC seems to function? Have you taken it out and made sure? If not I would check in to that. Is you check engine light on? If so, provide us with the codes. Also you say you have replaced some sensors, please elaborate more. It's easier to help when you're more descriptive and tell us what you've done already done so we can eliminate that as a problem.
