You could try taking off the IAC and cleaning it. Or at idle unplug the IAC and see if it stalls out.
Then take off the intake and clean it out really good and get all the gunk off the butterfly valve. I had a slight vibration at idle, plus my plugs had lived their life, so after plugs, wires, coil pack, IAC cleaning, MAF cleaning, and cleaning out the throttle body it ran like a brand new truck.
