2022 F150 5.0 L. rough idle at startup

[Aeroguy123]

I just bought a used 2022 f150 with 67k miles. I just noticed a rough idle right after startup. I can feel it in seat and door. IT goes right away after putting it in gear. Is this normal?

Use higher octane, Top Tier fuel,

We use 91 for daily, 93 for towing.

Started with 87 and the truck idled like a washing machine. Went away with the Ford recommended 91.

My 2023 Ford F150 -XLT has a rough idle at stop lights and when I’m sitting at an idle. I’ve taken it to the shop twice, and they’ve concluded that it’s common in the 2.7 Ecoboost engine. They even gave me the opportunity to sit in another 2.7 they had on the lot, and it idled rougher than mine. Many people have reviewed these trucks on YouTube, but no one has ever mentioned the rough idling issue.

Since when the Ford recommended 91 for 5.0?
5.0 idles fine on 87 if everything is ok with your engine.
