2015 Legacy 2.5i bucking at 25-30 mph

[MRubin78]

My 2015 Legacy 2.5 with about 95,000 miles bucks really bad at like 25-30 mph it feels like its intermittently missing 1 or 2 cylinders.
I've changed all 4 spark plugs (porcelain was a tad bit oily, probably valve cover gaskets), I drove it with a live monitor on scan tool and didn't see any misfires occurring, so I'm scared that my cvt bought the farm. If anyone has any tips or things I could check to further diagnose before I start throwing parts at it I would greatly appreciate it.
Later this afternoon I will attach a video of the car bucking.
Thanks,
Matt Rubin

Do you know if it is fuel or spark? That's the first place to start. Electrical components are easy to test. And does it smooth out past 25-30?

Same issue on a 2017 Legacy.
Dealer replaced coils and spark plugs. Runs perfectly.
