5.0 engine vibration
Posting for a friend .... 2015 f150 has a very bad vibration in the motor on cold morning starts!! Took the pickup to the dealer and its throwing codes that there's a misfire not only on one cylinder but all cylinders and there response was to keep driving it because they ( dealer ) and ford Canada techs were aware of the issues occurring with several other 5.0L 's but don't have a fix!! In my opinion this is not nearly good enough for a $50000+ truck ... Any ideas what may be the issues with this engine?

Is the bad vibration when the truck is idle, warming up? I had that problem last winter with my '13 5.0, it was routinely minus 20. It had to do with fuel icing. Rpms dropped and truck vibrated. I didn't take it in but there was clearly cylinder misfiring. Adding higher octane fuel or fuel line antifreeze fixed the problem. If they are experiencing the same issue, forgoing a warm up and just driving off also prevented the engine vibration. I suspect actually using the block heater may help. I havnt had this problem on my '16 5.0 but this winter was much warmer in the GTA

What Hctr154 said! Sheesh...
I would start with a data re-flash on the ECU.
