I have all kinds of problems with this car, but I have got everything sorted except for this. When I originally tuned the car I did Auto VE with the A/c off and had everything as far as driveability tuned where it was +-2 %. I then tried turning the A/C on and it was running super rich at idle and driving about 12.8-13.4 everywhere. I then went in and did an autoVE run with a/c on and got it back to where it needs be. Now when I turn the A/c off I'm idling in the 15-16 range AFR. Is there no other way to compensate for this? Or did I do something wrong with AutoVE?
Second problem is it idles great when A/C is OFF but when I turn it on at an idle it has a serious surge up and down and the A/c light starts to flash and will eventually settle itself out. Is this a timing problem or an airflow problem or both? What PIDS should I log?
