Misfire cylinder 7

[Motorcity muscle]

Hi! I have an 11 expedition with cylinder #7 misfire… this is after having random misfire… changed all plugs, just got truck and looked original… then #7 came up, changed all coil packs, rather be safe then sorry… still missing, changed out fuel injectors and it’s still #7 misfire… 205k miles, not losing any fluid, engine is quiet no loud ticking or anything but if you get up on it it bucks and shimmers! Been researching and got connections to check compression, neither one fit(04 or newer Ford 5.4l)… could it be rocker follower? Seen some videos on that and camshaft phasers, but again no noise, seems to run good after warm up, until you get on it!

Need to start a new thread, this one is from 2012 and welcome to the site.
