car stalls (shuts down )
i have a 2000 vert with 6200mi. it has many mods, h&c; ported tb;flp headers ; dbl roller timeing chain ;vararam b2; ls6 intake man;etc,etc. my problem is that the car shuts down when you come to a stop. it runs perfect when not in the a/c mode. if i come to a stop sign and push on the a/c button the car goes from 800 rpm to either 450 or 500 rpm or it just goes to 0 ,just like you have turned the key of. i don't know and neither do the gm mechanic or my tuner know whats going on. when not in a/c mod the car runs perfect. the car hasn't been driven much this year and wondering if the a/c compressor could be boggig down. any input from anyone would be appreciated . by the way the a/c works great and above 1000 rpm the car runs great but as soon as i decelerate and gets near idle speed the problem arises.

Is this a recent problem or has the car never been right since the head and cam install?
