My 94 would occasionally loose power when I was driving. Then it would start running fine again. It finally got a little worse, where I could stop when it was running rough so I could check it out. I put an inductive timing light on the plug wires. On the front coil 1 & 4 were firing while 2 & 3 weren't. On the back coil 2, 3, & 4 weren't firing. When it was running ok, all 4 were firing on the front coil, but on the back coil 3 & 4 still weren't firing. I'm not sure if the back coil makes any difference in the performance or just the pollution. I have a couple of ideas what might be causing this, but wondered if anyone has seen this problem or knows the most probable cause.
