2020 Lariet engine misses.

[Batman62]

I have a 2020 Lariat that the engine seems to miss fire/ hesitate when driving a constant speed. It occurs between 15-45 mph. I have to drive 25 mph on a military base and this happens nearly every day. It started to happen about 5k miles ago.
I took it to my Ford dealership and said they couldn’t find it.

You have to spell Lariat right or you will get kicked off the group!

Just a thought, could it be the engine lugging or the tranny itself slipping into and out of lock-up. Ford programmed the tannies to hold the higher gears to long (for mpgs) in my opinion, causing a lot of engine vibration, and stupid shifting at light accleration. When I'm in town or on a street that calls for 35-45 mph I lock out the top three gears so it will stay in 7th, and at higher rpms to stop all that mess. At 25 mph mine acts a fool if I don't lock out any gears. Hopefully it's something that simple for you, and it's easy enough to check out when you go to work tomorrow. Wish I could help you more.

Hesitation could also be due to the turbo needing to build boost?

Sounds a lot like what this topic is talking about: https://www.ranger5g.com/forum/threads/bucking-surging-epidemic.14581/

One member was able to have their dealer find the issue, same part fixed it for some others including myself.

Use sport mode when putzing around base.

Since it just started or got worse - maybe the trans learned your on base driving habits and is doing something weird with what gear or when it will downshift. Not sure on how to get it to forget that. Last car you could pull the negative terminal off the battery and step on the brake and it would dump that learned behavior.

I work on a military base also and before my tune, my truck would hunt for which gear to be in at 25-30mph. With my tune it resolved the issue

I know it sucks because you shouldn’t have to on a brand new truck, but the Ford Performance tune completely changed and fixed my truck. I had the same issue

Able to check the codes? Have money on a vacuum leak, they tend to act noticeable or worse at the higher gears/lower rpms.

Obviously you cant scoot it on base, but anywhere else, does it happen during decent acceleration during that mph zone to higher speeds? Or only putting around at those speeds?

Also as others have mentioned, does running it in lower gears help it?

I'd try sport mode or towing mode when in a 25 mph stretch. I tried sport mode an it kicked rpm's up more than I wanted an hitting the tow button split the difference an seems just right for me.

he's fine. what really decides if you are welcome or not, is damper preference

and we have seen recently, that the Damper President can be placed into a position of trust and ultimately a conflict of interest regarding any post referencing a damper.

I suggest curtailing his abilities to post in any thread involving a damper....or sell off his stake in the Damper and removing his from his truck immediately.

That stopped everything, Ha Ha.
