Misfire and spark plug recommendations.

[Brad Morrissette]

I recently picked up an 08 Eddie Bauer with 132k on the clock. Immaculate interior for 4K. Engine has a misfire on cylinder 8, causes the stutter/ hesitation or if I punch it a flashing CEL. Hoping it’s the plugs and coil boots rather than timing, but will do that if necessary. What plugs does everyone recommend? I have seen some people using the updated motorcraft plugs.

i cleaned the electrical plugs for the coil and injector with contact cleaner and pipe cleaners cut into 2 inch pieces. after an hour of work i cleaned both plugs on all 8 cylinders and the codes went away.

Another thread on here about my truck, seems like plugs first, then go to the injector wire connectors.
