I have a problem with my idle with A/C on. My setup is 2zz PFC. It works fine in the past, but just for the past few weeks the A/C idle up has been erratic and now my idle is 2200-2500 RPM whenever A/C is on. Is there any easy way to disable the A/C idle up? Since my idle normally is at 1100, I don't need the idle to be any higher than that.
