Well this is probably a dummy question but a search has come up empty. Running ECMlink v3. Car runs and idles perfect with the AC off. Now that its getting hot out, I turned the AC on and the idle jumps to a steady 2000rpm. If I sit still for awhile it will eventually go back down to 950 where it belongs. Idle between shifts is also way up to 2000rpm. Turn the AC off and immediately the idle is perfect again.

All of my searches came up with the opposite problem of idle dropping with AC on. The IAC is new and the car runs perfect otherwise. Drive it about 50 miles everyday. Thanks for your help! -Matt
