Backfiring sputtering problems
Hello yall I need some help.
Recently I just swapped my old 5.2 magnum for a brand new one from Napa. It runs great around town but when I floor it to get onto a highway or something around 3k rpms it like backfiring popping & sputtering. But once its under 3k rpms its fine. Anyone out there who knows what the problem could be? Still have the stock auto trans. All new plugs, distributer, cap & rotor all msd.
