I don’t know if I just have bad luck, or maybe I just drive like too much of an A hole. I have had 3 F150 3.5 eco boosts since 2012 (the 3rd being my 2019 Rap). Every one of them started idling a little rough around 30k - 40k miles.
Replacing the plugs always helped. Usually around that same time frame, I have a coil go bad as well…
On the Rap, replaced the plugs at 35k, smoothed things out a good bit. Just replaced the first coil at about 39k, and think I have another that will probably be throwing a check engine light within a few K miles. I might just replace all the dam coils in 1 go.
And I don’t even have a tune.
Full-race Geoff appears to have a good recommendation for plugs I will likely try next, post 3 in the link below.

Full Race's "Gen 2.5" Raptor build
Long time lurker, first time poster - this thread will document my journey as I build my Gen2 Raptor. "Gen 2.5" is the designation for combining the 2021+ Gen3 evolutionary improvements with the simpler 17-20 Gen2 platform. I'll be cherry picking the Gen3 parts-bins and using high quality...
