Arcing across coil terminals

Toolmanmike, I really love my Mac scope. I've found a lot of bad ignition parts, alternators, and fuel injectors with that thing and made a lot of money.
I realize most people can't justify buying a scope, but when you have ignition problems, you need to find a shop with one and have them troubleshoot for you.
You guys have spent 2 days guessing at what the problem might be while someone who can read a scope could find the problem in about 2 minutes.
