Been watching this thread. Finding the cause of a miss can be very frustrating. Hoping to learn something from your misery. I'll try to contribute: Can you narrow it down as to wich cylinder is missing? Someone mentioned hitting each one with a timing light. That sounded good. You can ground out each plug wire too. If you are brave you can just start pulling 1 plug wire off at a time. The getting shocked part is kind of a drag though.
