It sounds like spark jumping to a ground, or a mechanical problem. This would be best to have a shop check it out. It is going to take some time aand specialized equipment to diagnose.

All the little details,no matter how small, will help us to find the best diagnostic route. I'm glad that you were able to find the problem. The spark plugs will normally show the cylinder that has a bad head gasket.
