Sorry, I have very limited knowledge on this, just something struck me about your issue that made me think of reading about spark plugs, caps, and wires, any of the 3 can have resistors, but you only want it in one of the three, and that could potentially be an issue for you. It may not be. Just thought it was worth exploring the idea. Take a look at this thread, the knowledgeable people like Nessism and Steve know what they're talking about. See if any of that info seems to make sense with your issue.

Hey guys, in an attempt to stir up an old thread I'm having basically the same issues with #4 cylinder except that regardless of which boot I use #1 or #4 it does the same thing. With the boot fully on #4 doesnt fire, if I pull the boot off and just place it on top of the spark plug the cylinder starts to fire! It's almost like something is shorting out my ignition coil??? Any thoughts?

Run it in the dark with the boot in both positions. You are looking for spark escaping from the boot to the cylinder head.
