The coil packs are 2 staged. 1 or 2 off the coil packs are bad. Low side is fouling and when you hit higher RPM, the high side takes over, runs fine.

First of all, it's a 95 Firebird Formula. They have the LT1 which uses the Optispark distributor, not the coil on wire distribution system. Probably the Optispark died on you. My 95 was doing the same thing. Backfires, stutter off the line, even with the gas floored, bog from around 1500-1800, ran fine over 2k rpm. If you can do autowork yourself, you'll save yourself a lot b/c you have to remove the crank pulley and water pump to swap the opti. Also, buy an AC Delco replacement unit. They're costly, about $500, but they're quality units. Will last 150k+ miles if maintained, cap and rotor replaced, not leaked on, etc.

A bit surprised they let drunk people post questions on this forum.....or 10 year olds......?
