Sounds like you have good plugs and wires, with it running so smooth indicates that most primary systems are in spec. IE: timing, fuel mixture... Your problem statement should be, "low power at idle" I don't necessarily think the IAC is bad, it might be bound up in carbon. The air passages could be blocked by carbon.It revs fine too, I can punch the throttle and there is no stumble at all, idle drops right back where it should. Could that still be IAC?
