Hello everyone, I have a 2013 Sierra 6.0L I bought with a cam squeal. I replaced the cam with stock replacement, new lifters, and I am now chasing an issues causing the truck to spit and spudder and pop on accel. Truck will start right up but then when idle dies down. It will start to miss and shutdown cylinder by cylinder and die. I replaced all 02 sensors, (still have codes) and one camshaft position code. I don’t have the truck in my possession anymore but working with the new owner chasing down the issue. If anyone knows what’s going wrong? Please help. Truck will run great after you get past it popping and do 80 cruising on the highway with decent gas mileage?
