Seems odd that a bad wire (or one bad plug connector) would affect only one plug when there are two in series, but it is exactly how it worked for me. It ran as yours does: idled on 5cylinders, but easily made highway speed on 5, just a vibration at lower RPM, but never seemed to fire on all 6 (the engine management will cut injection to the misfiring cylinder so it doesn't get a second chance anyway, ... does save the CATs from damage though).

I wasn't disagreeing with Arthur, primary problem was terminology. Second problem was me not believing I could have received defective parts. But as you can see in my response to Arthur's last posting, moving the coil to a different cylinder pair did result in a 'no spark' on the other cylinder. So the problem moved with the coil, indicating that one of the new parts is broken, and I'm leaning toward the coil being damaged since boot has been replaced multiple times.
I work in technology so I completely understand broken new parts and confusing terminology. Hopefully it can still benefit someone else to know that just because the part is new doesn't mean it is going to work.
