93 3.1 troubleshoot

I own a 93 with a 3.1. The car has a miss and backfires when accelerating. If you accelerate up to about 3000 rpm the car will smooth out and run great. I have replaced the coil packs, the mount bar they are on, plugs and wires and still have not resolved the problem. Anyone have any ideas?
