2015 f150 5.0 rough idle

Having rough idle issues when hot #2 cylinder shows misfire at idle on ids using misfire monitor relative compression test shows 4-6% drop on test have changed all plugs all injectors as well as cylinder #2 coil wondering if I have internal engine issues these engines are not really known for having mechanical failures what should I be looking at this point

Do an actual compression test. Also try swapping the coil and injector.
