This shows from startup. Just sitting and idling, to a full stall, then restarting.

Well, that wasn't as bad as the crankshaft sensor. Plugs up next. Looks like we had at least three different types of coils
(#5 is the one I had just changed)

This is for an 04 Expedition with the 4.6....but it may help. It is for a P0320 code and how to pinpoint, etc.

Wow, that site is awesome. I've found they also have the 5.4 on there too. Will definitely be digging into this.

Removed the spark plugs without too much drama. Again, seems like a mix of parts and ages. Two different types of motorcraft platinums, an Autolite, plus the Bosch Iridium that I just put in there while troubleshooting this. Gaps weren't horrendous, but they were all over the place. A couple were way wide. I really don't like how much sludge and dirt there is on the tops and down into the threads.
Going to hit everything with a heavy blast of Brakleen while it's apart and then blow it out with the compressor. Probably give the openings a little toothbrush scrub. Got 7 more plugs to match the new Bosch and 7 more new Accel coils to keep it consistent. Will do oil/filters etc afterwards. Fingers crossed that something in all this is the root cause and will be resolved.

I don't want to jinx it, but after doing:
Replace:
Ignition Switch
Main Junction Control Box
Crankshaft Position Sensor
PCV Valve
8x Bosch Iridium Spark Plugs
8x Accel Ignition Coils
Cleaning:
Valve covers
Spark plug bore thread
Battery and ground terminals
Changed:
Air filter
Oil Filter
Oil
... It's working at the moment with no stalls/misfires. The problem is only noticeable when it's totally cold and running for the first 15 minutes, but the first fire up after all the parts when back on was pretty good. Some smoke in the exhaust, almost certainly from the brakleen I was cleaning the valve cover and bores with.

Good job ! Any idea how old the fuel filter is ? To release the quick connect lines just push the blue buttons on the fitting and pull.
