MISSING PROBLEM WEAK SPARK AT COIL P

1992 Mitsubishi 3000GT

Electrical problem
1992 Mitsubishi 3000GT 6 cyl Front Wheel Drive Automatic 127000 miles

The engine has a miss some times I replaced the spark plugs and wires. When it was missing I pulled of spark plug wires from the coil packs and found the 3, 6 coil pack was not sparking, then it would spark but weakly, I replaced the coil pack, same thing happened. Sometime a good spark sometimes weak or no spark. I have check all wires and connections. What should I check next?
