2001 5.4, 6&7 Cylinder Misfire
Hey All! Was wondering if anyone could help me out? I've got a Cyl 6 and 7 misfire. I took the coil and spark plug out for both and noticed that the plug was full of dirt and some water.
I cleaned the plugs with brake cleaner (cause i just put them in bout 6 months ago) and cleaned the coils. I put them back in and started the truck, and it did well for a bit....then the same thing. Anyone have an idea of what it is? I'm thinking new coils, but I don't know. I've been told that the Fords have a roadspray issue with the plugs (thanks to design). Any help is greatly appreciated! Oh, one more thing.......if it's the coils, aftermarket or stick with oem? THANKS!
