Here's the video the other "YouTube star" was referencing.
My old '71 Cutlass wouldn't start sometimes when it it rained really hard. I knew what to do.
I'm impressed that this guy found the issue on the the F150 at all.

Y'all keep driving your Jeeps in deep holes. ?
I recall years ago a teacher talking to us about how gathering all possible information can be critical to a solution (like most people on fakebook and even here sometimes simply ask "why won't my car start")
The smallest little detail can be important -
A person came into a shop complaining that every time he stopped at a store and ordered a quart of pistachio ice cream, his car wouldn't start when he went back out to leave with the ice cream.
It appeared to be flooded (ok, kids, talking CARUBRETORS here)
He said that it only happened when he bought pistachio, no other flavor.

Trying to get beyond the potential humor in the story - they asked the guy for some more details.........
Turns out the other flavors were already packaged and ready to go. He'd grab a quart, pay, and leave, no problems. Car started ok.
But the pistachio was not a big seller so he had to wait for service to get it hand packed into the container and it took several extra minutes. Got back to the car didn't want to start.

Finally having some idea of what may be going on, they asked the guy to bring the car by so they could take a look.
Looking at the car, work had been done to replace heater hoses - which on a Ford (and some others) were routed up into a clip that held the heater hose against the choke thermostat. Whoever replaced the hoses didn't put the heater hose back in that clip and saved a few inches of hose.

Anyone figure out what was happening?

When I took my JT into the shop for the misfire I had gathered information and had so much detail they could actually recreate the conditions and force a misfire. Even if it hadn't behaved for them (or misbehaved) there was enough information for them to find the issue.

Just saying - don't say "my car won't start" or "I have a misfire, what's the problem" and leave it at that.

Took it in today for the cluster replacement. This is the third cluster installed in this jeep. Working as it should so far.
Did they transfer the odometer mileage or just put a sticker in the door jam

Do they even have to do a transfer?
I find mileage listed under PCM in several of my logs -

Fault code: P0300
PCM Mileage since MIL On: 0.00 miles
PCM Odometer: 2662.40 miles
Open Loop - Bank 1: No
Closed Loop - Bank 1: Yes
Open Loop due to Driving Conditions - Bank 1: No
Open Loop with DTC - Bank 1: No
Closed Loop with DTC - Bank 1: No

If unrelated, any clue as to what that's about?

Not sure about all that but my check engine light read as something related to the radio. They said the only way they could order the new part was to have it programed with my current milage at time of order. The jeep has about 700 additional miles. on this replacement. 1500 on the previous replacement.

PCM logs it separate from the instrument cluster and does not report it for the instrument cluster use. Basically the cluster and PCM record mileage separately.

Hootbros statement is correct.
I didn't have a doubt about that. Just thinking how simple it could be to swap clusters, plug it in, and the mileage would propagate out to the cluster - but then, I'm sure there's solid reasons to keep them distinct. One of them would be in case of the need to replace the PCM, among other reasons.

There may have been a few vehicles in the late 1990's and maybe 2000's that could swap a cluster and mileage would transfer but do not hold me to that. I know pretty much anything in the modern era at least the last 15 years or so, cluster swapping meant reprogramming if you wanted actual mileage to be accurate.

Very little I wouldn't take your word on.
If you came in and said you had women figured out - that's another matter. No human male is THAT smart.
