2003 Expedition with code....

P0307 - Cylinder 7 misfire

Ok, so is it my COP (Coil over plug), the spark plug wire, or the injector? No other info was given on the scan tool.

Any input, as always is appreciated.

Craig

Is this a 5.4? If so in my experience I usually replace the spark plug, wire, and coil. Unlikely that its an injector

Yeah, it is a 5.4, I guess that would have helped to know. I'll have to see about changing these out.

Thanks,
