2012 5.4 triton (Gator), light misfire (?) vibration at idle

[Adieu]

Its not REAL rough, just less smooth

VCTs on the 08+ Tritons were no longer easily accessible as the valve covers were redesigned when they went away from the 2 piece spark plug. They now require the valve cover to be removed. Not terrible, but not nearly as easy to change. With those miles, I would do spark plugs and coil packs, the coil packs are cheap and a common point of rough idle or miss on acceleration.

Actually.... unless you go with China coils, coilpacks are pretty dang pricey
