Re: Coil On Plug Replacement 2004 4.6L ??
Hello, I am thinking you are describing what Is a fuel rail. There are on each side of the engine on top and connect to the fuel injectors. I dont know exactly how your 4.6l is built but probably very similair to my grand marquis 2006. It is somewhat of a task to change the plugs but if you have some extensions and elbow joints to use with the socket: you can get around it without having to remove the fuel rail and other stuff in the way. A air compressor would be good to blow out stuff also before actually removing the plug after you remove the coils: dont want debris in the chambers. I would do some more research and try to get a pic that describes what the engines looks like and its components. I also use black tape to wrap the socket and extension so that it dont come off inside the plug. You could also remove the spark plug sockets interanl rubber insulator to make it a little easier when you put them back on. Long needle nose and angles ones make for an easier job to reach in there and remove a dislodged socket or plug. good luck and hope this helps.
