Hi Scotty! I really enjoy your videos. I learn a lot. Now I know you're pretty busy, but I was wondering if you could possibly answer a question. I have a 2017 Ford F-150 with the 5.0L. it has 116,000 mi and is an automatic transmission. The issue that I have Is that it will sputter and stall out. It does this intermittently, not every time it's driven. When it happens there RPMS drop to between 500 and 300 RPMS. I have been to the dealership for this problem four times. The first time they said it was the throttle body and the butterfly valve was sticking but I clean that myself, so I was fairly sure that wasn't an issue. Sure enough, after that visit it started doing it again. Another visit Spark plugs were changed and another trip the ignition coils were replaced. And the battery has been replaced in July this year. I've tried adding sea foam fuel additive to try to see if that would fix the problem, no. I don't know what else to try. Don't know if you have experience with this type of issue and can advise me of what it may be or what I can do. Again I really thank you if you can answer this question.

The issue that I have Is that it will sputter and stall out.
what happens after? Does it start right back up?
Does it stall when you're driving? Idling? heavy load?
Several things can make an engine stall. Fuel starvation, bad electrical connection, failing charging system ....
I would get a diagnostic tool to record critical data when it stalls out.
It starts up immediately after it happens. It only happens when at idle. My next thought is to replace the fuel filter?
that's a big job. I would measure your fuel pressure first. Merry Christmas.
