If a spark plug wire or coil pack is arcing then no spark is at the plug inside the engine, the spark will ground to the first place it can.
Any codes been set?
Remember, there are two plugs to a cylinder. If one of them coil to plug wires are arc-ing to ground then the engine may still run without a miss. Also, I would not suggest you spray any WD-40 onto a wire that arc's or you might get a flareup (fire). Good luck!
