ok here we go i got an msd 6al box. im not getting any power at 2000 rpms it backfires and losses power. it was fine when i ran it without the box. now without the box hook up in runs like ****. i think my box screw something up. it has a pretty new tune up
i take it up to 2000 rpms and it sputters and back fires. i change plugs,wire ,cap, and rotor. im thinking maybe i shorted out the distibtor module now if i did will it still start
