If you were local I’d have a tech scan it for you for free.
However most dealers including ourselves will waive the diagnostic fee for you if you do the repairs with us. The things mentioned so far aren’t that expensive to have done. Good luck

Its going to be the throttle body or the spark plugs. My guess is the plugs. Ecoboosts have a tendency to open the gap on the plugs with relatively low miles. I wouldn't waste money taking it to the dealer. Spend the 50 bucks and 30 minutes and change the plugs and see if the problem goes away.

I would get forscan and an adapter for the odb2 port. You can read codes and change lots of cool parameters.

Was it raining? My 17 eco boost did it while passing during a rainstorm. Only happened once. I was told my truck will need new plugs ar 90k miles...

They were known for spark plugs issues with your same symptoms. And they are due anyways.

Definitely spark plugs, I just changed mine and was having the same issue intermittently. It was worse when the engine was just coming up to temp. This is because the ecm enriches the fuel mixture until at full operating temperature. I regapped the plugs at 20k because the first few years were gapped at .050” which is huge for a turbo motor. Now they come at .032”. Looking at my old plugs (70k) the ground strap had a pit eroded into it that I’m guessing was .010-.020” deep. New plugs and running like a champ now.

I will change the plugs and see if that solves the problem.
