I had my ac serviced about a week ago and the car ran fine for a couple days. One day while driving home I turned on the ac and the rpms dropped very low, to the point of almost dying out. I turned the ac off and drove home with no driveability issues. I cleaned the IACV and AAC valve as per Robo's write-up. However, there is no change when I try to adjust the idle screw either in our out, nor is there a change when I pinch the hose or disconnect the harness to the valve. Car starts up every time hot or cold. The car idles fine (a little lower than what was originally set before the ac issue) and boosts strong. The issue only manifests itself when the ac is turned on. Any suggestions or advice in helping correct this issue would be greatly appreciated. Thanks.
