2016 XLT running rough and stalling
So about 2 months ago I bought a used 2016 F150 with a 5.0. XLT trim with the FX4 package. Had 38k on it when I bought it. Now has 41k. Problem started a couple days after I got it home with running real rough. Got home from dinner one night and it died on me after I had backed into my driveway. Thought it might have been either bad gas or maybe condensation in the fuel tank cause it sat for a while at the dealer for a while before I bought it. Ran the first tank of gas through it and put in a bottle of Techron to see if that helped and started running mid grade fuel in it. First time it stalled on me was maybe a week after I got it home. Called the dealer I bought it from and they told me to bring it to their service center who in turn told me to bring it to Ford because its still covered under the 5/60k factory warranty. Brought it to my local Ford dealer and found out there was recall work that needed to be done and that the truck came out of Canada. Told them about the stalling and rough idle as well as some transmission thumping that I had noticed. They ran a diagnostic on it and couldn’t find anything. No stored or pending codes in the computer. That was about a month ago. It would stumble a little here and there but it was something I couldn’t readily reproduce, until Sunday. The rough idle came back and stalled on me 3 times. Monday it stalled on me again after getting home from work. And today was the same thing. The truck has never thrown a check engine light any of the times it stalled or started running like a turd. And it only does it when it reaches its regular operating temp. Under load it runs like a champ. Gets up and goes like a scalded dog. I have video of he tach needle bouncing and of it stalling out. It’s to the point now I have to 2 pedal it when I come to a stop so I can feather the throttle so it doesn’t stall. It’s going back to the dealer for more warranty work on some parts they didn’t have the first time it was there and I already talked to one of the service reps about the additional problems I’m having. I’m hoping with it happening consistently since Sunday that they can reproduce it at the dealer. Regardless I’m showing them the videos I have so they have something to go off of. Has anybody else had this issue? And if you have, what was the remedy for it? Thanks in advance.

With that being said, it might be a throttle body problem.

I'm pretty sure the IAC valve went the way of the dinosaur once the drive by wire throttle bodies were introduced. They control the air flow and yes I think it sounds like a bad throttle body as well. That's a guess based on your symptoms and the fact you have to hold the throttle open to keep it run.

My girls old man cleaned the TB when he was helping me with an oil change yesterday and it already seemed to be running better. Only time will tell and it just went back to the dealer for them to finish some recall work they were waiting on a part for. Once I get it back and can put some miles on it I’ll be able to tell.

I think who ever had it before me didn’t take very good care of it. It’s on me now to get it fixed because I didn’t do my homework before hand. Live and learn. The oil that came out of it was nasty.

I've seen many intake tracts get gummed up by those things, usually when the filter is over-oiled. It accumulates over time though. Not your issue if it had a normal filter prior.

So I brought it to a different dealer yesterday and go a call from them today saying that the OBD port has bent pins in it from somebody forcing a scan tool on it. They ordered a new one that should be here tomorrow. They also said that it was throwing codes but because of the port being messed up they weren’t able to read what the codes were. The rough idle was also replicated with them so they now what it’s doing first hand now so hopefully tomorrow I’ll have more answers
