Yanked the #3 ignition coil and found that it looked like many others I looked at online, all cracked and trashed. Put a new one in it and after a minute or so of 'figuring itself out again' the engine once again runs like a sewing machine. Most excellent.
To clear the code out of the OBC, I hooked up the Durametric tool to it for the first time. Very cool accessory to have I must say. It doused the CEL, cleared the misfire codes and while I was at it, I killed off the Airbag light from passenger seat relay fault....Nice. I knew that thing would come in handy. Too bad I accidentally switched my speedo/odo to Kilometers..oops. Just a reason to use the tool again I think.
