Forgive my ignorance, A/M ignition

Wow ReTED, you should make that a sticky. I thought I was a little sparse in my description, but you have put me completely to shame!

Kudos to you!

The only question that I have is:

I thought that the stock coils fired using wasted spark. This is usually configured so that the current must pass through both plugs. It seems strange that a wasted spark system could possibly fire on only one of the plugs (are you sure about the cause of this symptom)? I am using the stock ignition and I only get misfires if I lean the mix up too much. Otherwise the engine purrs as smooth as glass. I think it might be more of an ECU issue.
