Yea, I forgot about that one Tackle. That's if yours is suffering the old "burr problem" deal. It was a robotic mistake during assembly. Good to see your still around btw.

Ok. Amazon actually dropped off something before noon for one, made me happy!
So I plugged in the obd reader and went to the codes section. No stored codes. Then I went to the pending codes section. No pending codes.
🤷🏼♂️ Lol
so then I went through I/M and the other tests. I took pics of the screen. I did some quick googling. So it looks like it may be EVAP related? Can that really cause a stutter?

I once had a misfire that wasn't constant enough to pull a DTC. My truck had no codes, but it would misfire occasionally.
@Jbrew taught me to accelerate to 44mph, just before it kicks into overdrive and hold it there to force the misfire. It worked for me and I was able to force the code out which was a misfire on cylinder 3 I believe. I could be wrong about that part.

Well guys, once again thank you for the help. Of course I drove it a couple of miles yesterday and it was fine lol.
so I’ll keep on driving it like you recommend and I’ll try this trick to see if I can get it to “cough” lol.
updates to come.
edit: my wife came down with a rare spine disease so I’m trying to save money but I’m going to start buying (or trying at least) to buy a couple Motorcraft coils every paycheck and just replace them all and be done with it. Plugs too.

Yeah, like was mentioned above, just before OD and in OD is where it shows up the most. I just had a #7 misfire, and rolling down I-80 at 70, going back and forth into 3rd and OD made mine illuminate pretty quick.

LOL. These trucks shouldn't leak anywhere...it's very rare. I guess the most common is a coolant leak behind the water pump into the block cavity. The o-rings (2) fail at the heater core hard-line connect there. You shine a flashlight behind the alternator into the cavity for evidence...it'll be wet. Also, if your intake is composite, they can crack with age. But other than that....
