backfiring fixed

[shelby2]

i found out the problem of why my exhaust was backfiring. i turned out to be a bad coil and it was not firing full strength every time. occassionally it would backfire and throttle response was poor. i put on a brand new msd 6a box with blaster coil and problems are gone. i can definitely feel the difference in throttle response and drivability, of course the msd box is probably the reason. it does still surge a little and die ever once in a while and i feel it is from the o2 sensors. one of them has a frayed wire and i feel it is the problem for that. i am going to get new ones and see if it fixes that problem.
