Hey guys,
I went through the posts looking for a similar condition and found one with no help for the problem. Hopefully somebody has run into this before and could shed some light on it for me. I have a '00 Corvette that I did heads and cam on and everything is fine except when I turn the a/c on it turns right off. The system worked fine before the tune, I have to be missing something I just don't know what. There are several things that are very weird about it also....no matter where I set the target idle with the a/c on it will only go to 750 rpm. If I raise the rpm over 1000-1100 rpm the clutch will engage and the air works fine. The system is fully charged and the pressures are 32-35 and 180 +. When the a/c is cycling it is blowing 40 degree air. If I let the car come back to idle the the clutch will dissengage, the light will go out on the a/c head, but the car still has a load and draws the engine rpm down. If I turn off the a/c switch it pops right back up to the target 825 idle spec. I have taken the torque management out, put it back in, changed the timing at idle, air flow numbers, a/c bump....I am just out of ideas. Any help would be great.
Thanks in advance,
Joe
