I looked at the trans log and I don't normally look at most of the items you logged so I'm not sure they are telling us anything...I thought the misfires you mentioned were a big blip in the log which usually indicates a disruption in the data stream while logging and not a big deal.
But your's were steadily recording misfires, that is the first time I have ever seen that in a log. It's looks legit.
I know you haven't had flywheel or torque converter work. ANd I'm not sure about any driveline work but if something is off in the rotational parts sometimes that can throw off the crank sensor readings...This is a long shot. But using your X4 you can do a "crank relearn procedure" I have never done it with the X4 but that can help with misfires with the ford logic
It's kind of complicated but the crank sensor is expecting to see certain rate of speed depending on conditions and if it doesn't it can record misfires and make the car run rough...You should do the procedure.
Update : still sputtering .. stalling after applying new update
Can you think of a reason it would NOT log the misfires on the other two CFG files from you and Torrie? that's whats making me all itchy atm .. but i will pull the front three plugs after i get replacement boots.
i may make a new CFg file again and just import a few standard things and see if the misfire is a fluke on THAT cfg file i built. make sure this is not a false flag ..
New question HOW dependent is my tune on the gap being .28 ? I do not expect that my current gap is bad, but i will need to gap the new plugs myself and i suck at it.
I will also do tghe crank relearn, no work has been done in the engine, but i may start hitting it with a sledgehammer in a few more days.
today's experiment will be to load the tank with 50$ of 97 octane. if it get way better the spark plug idea gains a bunch of merrit.
