Did you unplug a connector with 3 wires or 4?

Pick yourself up a can of Berrymans B-12 Carb Cleaner and clean out you IAC valve (Idle Air Control). I'm betting that will fix the idle swell. I've had to do that with almost all our vehicles that have one. Carbon builds up and keeps the stepper motor from being able to move the valve mechanism freely.
