OK this has been bugging the heck out of me....

If i start my car with the AC on the car will run lean in boost, Idle like crap and through a check Engine light....

I have determined that the Xede boots in a bad state or not at all. If I restart the car with the AC off the car start fine, also I can turn on the AC after the car is running and Im fine.

Anyone had this problem? Fixes?

My check engine light is PCM low voltage or something like that, I have to reset it tonight So I will get more detail and post it.

The car needs to be started with out the a/c on. The recommended start up procedure is turn the key on, give it 3-5 seconds, start the car. If the LED is green, it is on and working. It could also be that the car is running lean on start up too. I would try the new start up procedure, if that does not work, add some fuel.
