OK, was running great when all of a sudden running crappy, white smoke smelling like fuel from the exhaust. Figured no big deal, I've got a hung injector so I replaced them all. No dice. Thought maybe the pressure regulator was ruptured, replaced it, still no joy. Damn. I guess I need a PCM. Put in a reman. Guess what? Sounded great on first start up them, same same. Last code I remember from the original PCM was left bank rich, new one hasn't run long enough to set a code. I don't want to run it too long that rich as I figure it will trash the cats. Any ideas???
