Hi, have a problem with a 1999 Trans Am that seems to increase idle intermittently when the air condition is turned on. Had the vehicle serviced by a speed shop who were utterly incompetent and couldn't resolve the issue. Did a comparison on a base idle and from what i understand most of the values are zeroed out concerning the AC. This is an area I need some help with the car runs great untiL you turn on the AC. I have VCM Editor file from the car I'm sure most of you are more experienced then I am. Thanks
