Mine is doing the same thing bro. I've changed the plugs 3 times. No change. Techron in the gas, no change. I'm about to do ignition coils, fuel filter, intake and throttle body gaskets and valve cover gaskets, also 2 new precat o2 sensors and possibility delete the cats. If none of that fixes it, I'm thinking the head gasket is bad or a burned valve.
