I need some help with an ly6! I have an 07 NBS 2500 HD Gas with an LY6. I've done a VVT delete and installed a sloppy stage 2 cam from trick-flow and new ls7 lifters. Deleted the vvt in hp tuners. It cranks and runs for about a minute then the check engine light will turn off and the truck will cut itself off. It has a decently smooth but choppy idle and runs as it should for the minute that it runs. It doesn't seem to be a tune issue. I've also noticed that the check engine light will flicker not in a way as if it has a misfire but like an old horror movie light fixture. None of the other lights on the dash will do this. The only code of concern was a p0340 cam code. Also if anyone has a diagram of the ECM pin-out for the truck id like to check my voltages at the ecm. Any help would be greatly appreciated! The truck is getting in the way of starting one of the several major projects I have sitting up.
