Hello: You might check to see if you have the proper spark plug wires. You should not have solid core wires. They should be of the resistance type. Possibly bad coil or ign module causing to much dwell, hence to much coil saturation. Everybody likes high voltage to the plugs, but to much can be a bad thing
good luck
