96 caprice classic 5.7. lost fire, I've had a misfire issue before and after reman long block install. had it with original delco and acell that was put on during engine work. they installed the water pump drive gear seal backwards, so that might explain acell going bad. it had been running rough and giving a hesitation, but never lost spark. I've ordered a new opti(chandler to get by for now), delco coil, and msd wires. Am I on the right track? please help!
