Whenever I drive somewhere and park and let my car idle for a while it wants to start misfiring. It will miss for a couple seconds then go back to normal for a while then misfire some more then back to normal and repeat. Has anyone else had this problem?

I am pretty sure that the iac needs to be replaced because the car will surge a little at idle at athe stoplight or somethingthe when the a/c is on, so could it be causing this too?

Misfire is usually a COP, have you pulled all the COP's and plugs to do an inspection? might be something down in the SP hole.
