    I'd hook it up to Ibeat (dealer software) to check for codes and verify settings.
    Also look for intake leaks.

    I would also add checking the fuel pump as well. If your not aware it can slip in its mount.

    Sounds like your intake boot is cracked

    Like TheDude said, cracked or loose intake manifold OR clogged up fuel filter. Mine has clogged up twice, and it was back firing, popping, lots of weird stuff, a new filter cured it both times. These filters are so small, there's not alot of life to them in these dirty tanks.

    ok,have an update.TheDude sent me to investigate the intake manifold.when i did so,i found the top of the rubber boot slightly seperated from the throttle body.loosened clamp and fell back into place.very simple fix!i dont know why it back fired so violently,but running fine know.thanks for your fast response.

    After I ran real hot one time, my intake manifold gave up. When I got a new one, I tied it to the head to keep the vibrations from shakin' it so much.
