Help with code number P0304.

[jpadelli]

I have a 2000 Ford explorer with the 4.0 OHV V6 and I have been continuosly getting the code P0304 which is a misfire in the 4th cylinder. i have changed the spark plug, wires, coil pack, and the intake manifold gasket and it still keeps coming. I have no idea what to do next. Can anybody show me with pics how to replace a fuel injector please??? i need to get this fixed before i head off to boot camp and my wife is left with an issue. thanks to all who help.

Welcome to this forum! I've renamed your thread, and moved it into the EEC-V section.

How did the plug look? Cracked heads or head gaskets are common which usually fill cylinder with coolant on startup and create miss that goes away when warm.

the plug looks fine the only thing wrong with the plug is that the tip is white meaning im running lean in that cylinder.
