So it could be the IAC valve, possibly dirty and is sticky, cleaning some times helps but if it has never been replaced it you might just replace it and make sure the passages are clean befor you put on the new unit. Other things could be the TPS, ACT and the ECT. If any of those is sending an incorrect signal it can cause the ECM to make incorrect adjustments to idle, air fuel mixtures timing etc.
