Why are you so sure, your problem is related to Idle Speed Air Valve? You said, you have an intermittent miss. Typically intermittent miss is relatedd to a failure of primary ignition circuit.
I refer you to Haynes manual. It has a good chapter on troubleshooting ignition system for your model. It will take you about 30 min to an hour to fully test your ignition.
