89 Cavalier 2.0 4cyl ohv distributerless

Last fall, I pulled off the crimped on metal piece off of the spark plug wire and I re ghetto crimped it back on with some pliers. It worked for a long time until, I got stuck in the storage unit lot in a snow storm with bald tires. I had to get it in my storage space so I flored it to try to gain some traction and I melted my wire off of the metal piece. I was then running on 3 cyl. Later on I replaced the wires and plugs and now it feels like I'm running on 3 1/2 cylinders. No power what so ever. Wires are in the correct order. Otherwise, it would back fire. Maybe a bad coil pack? Any ideas?
