Surging Idle

1st warm day here so I tried out the AC - it works lovely. One issue, when decelerating the tach hang @ 2000 rpm and I have to blip the accelerator to make it come down. This only happens with the AC on...Is it the ICV and if so, where is it on this car? I thought the ICV would act up with or without the AC.

Please advise.
