P0354
Good afternoon all, new to the forum and I'm sure there are other threads on this, but figured I'd start here by posting then search and try to find my answer.
I have a 2015 F250 6.2L, last Sunday noticed hesitation and a miss, scan the truck find P0354 Ignition coil D primary/secondary circuit. Today I replaced the 8 coil packs and 8 top plugs, I'm aware of the other 8 plugs but due to some finance issues and remodeling a bathroom (besides the point). I figured I'd go that route and slowly eliminate issues before taking it somewhere, I'm definitely a backyard mechanic who probably spends more trying it myself then having a shop look at it.
After 8 new coil packs and plugs on the top end, found alot of corrosion in packs and on plugs,but noticed the truck not missing as badly, but can still feel it. So what I need some advice; do I replace plug wires and lower plugs? Or is this a bigger issue and should take it to the shop and further raise my debt ceiling?
Again new to the page, and figuring things out. Thank yall in advance.

Did you install Motorcraft coils and plugs? Aftermarket coils are a NO-NO! I would do an injector buzz test (which most DIYers won’t have the equipment to perform) to see if one of the injectors isn’t performing the same as the others (or bleeding down). Also can’t rule out a mechanical issue, like a non-sealing exhaust valve or poor compression on one cylinder.
