car dies at lights with AC on...
Ever since I had a cam installed my car will die at stop lights/signs 9 out 10 times. With the car at idle I can turn the AC on full blast without any issues. It's only when I come to a slow stop it will die. If I have the AC set to the "AC" setting and on low I can get away without the car dieing. Any other settings and the car dies. Any ideas?

Too many variables. It could be loss of vacuum, or a charging (alt.) issue, or a problem in the A/C system itself (doubtful). I'd look for a vacuum problem unless you also swapped pulleys recently.

I did install just the ASP crank pulley when I installed the cam. I do have a M6 so I didn't think the pulley would cause me any charging issues. Do you think adding the ASP alt. pulley would help?

My guess: Crankshaft Position Sensor
I had the same exact symptoms, no SES ever came on. The dealer found it though. The tech said its one of the items that sometimes won't flash a code. Considering you just installed a crank pulley and a cam it could be it.

Crank position sensor huh? I'll check that out.
Yes, I did drill the TB blade so it would idle after the cam swap.
