My lt5's #4 cilynder is missing a lot but not all the time. I replaced plugs, wires and had all injectors cleaned and tested but no change. If i allow #4 spark plug wire to arc to ground the engine will die. Any suggestions???

It might be a bad coil. There is one coil for every 2 plugs. The coils are under the plenum.
