Angry Surging Idle/Throttle-Help!

My problem is that intermittently my truck has a surging idle. It does not do it all the time, but I will get an idle that fluctuates between 400 rpm, and 1000 rpm. So far it has not stalled. Sometimes it will also rev up to around 2500 rpm as I'm coming to a stop, and push in the clutch. After it goes to 2500 it always comes down to around 650. I have replaced the TPS, Map Sensor, Idle Air Control, cleaned the throttle body, changed the spark plugs, and reset the APPS sensor. I'm not getting any trouble codes, and it runs great except at idle. I get no hesitation whatsoever going down the highway. I have had it at the dealership, and they can't get it to recreate the problem so that they can investigate. It does it probably 2 out of every 5 times it is driven. I'm getting really frustrated at this point. Does anyone have any suggestions?
