I'm not sure if this could be the problem, but this morning I cleaned/re-gapped the spark plugs, and after doing so I decided to check the spark. When I checked the spark it is jumping all over. It's not jumping the center and groung electrode like it should be. Instead it jumps all around the ceramic insulation around center electrode, and I'm talking about 1/8" down the side of insulation. What would be causing this and how to fix it?
