I have a 2016 f150 sport 4x4 with the 5.0 in it. I took my truck to ford to figure out this problem im having with the truck. I'm looking for answers on what it could be because said they can not do anything if its not happening when the truck is brought into the dealership. So when I'm at a stop but truck still running it will bog down and just shut off. Please help anybody might have an idea. I have changed plugs cleaned mass air flow sensor changed air filter put 93 octane in it and also injector fluid and nothing has seemed to work.

 

I would be looking at the fuel pump. Do you have any way to monitor fuel pressure, say with FORScan?

 

No I do not have any way to monitor fuel pressure.

 

I'll look into the fuel pump though.

 

does it pop up on the instrument cluster " Auto Start/Stop shift to park to restart"? I am having that issue. it will rough idle then just die. it does it in park as well. no codes, nothing but that pop up. I replaced the battery " not quite 2 years old" it went away for over a week. I went to Mccdonalds" same one it did it the first time at 5 times in a row" and bam it did it again.
I get away from that area and the rough idle is gone. So out of curiousity I go back through that mccdonalds and like clock work it dies again. Is it possible theres some radio frequency causing an issue.? or just pure coincidence? 1 time fool me once, 2 times fool me twice, three times theres something fishy.

 

his truck doesn't have auto start/stop

 

Maybe a dirty throttle body?

 

Can you video it for them?
