I have an 02 f150 4.6l v8 and am getting two codes, P0304 and P0316. I need to find out the cylinder layout so i can change my coil pack and plug in cylinder 4.

 

the #1 cylinder is on the passenger side closest to the radiator. #2 is directly behind it followed by #3 and #4 is closest to the firewall. The #5cylinder is closest to the radiator on the driver side. #6 is directly behind it and #7 is behind #6. Finally #8 is closest to the firewall on the driver side.

Regards

i am having the same problem with my truck with the code saying it is miss fireing on number 4 cylinder and a miss fire in the start up can you tell me if this means i need to change the coilpack and the plug or just one of them ?

 

Can't tell yuh sh^t without more info. You failed to fill it in (Top right corner). You have no sig? You haven't even posted what vehicle ?? Are you sure you have coil packs and not a COP ignition? What year ? Engine? What were the exact codes on the scanner? Not the defs - The codes.???

Have you used the search bar?

 

I started with changing 1 plug and pac and it was still doing it so i changed em all and the problem was solved.

 

You don't have packs - Packs drive 4 -6 cylinders in these trucks. You have a COP system = Coil Over Plug. You changed one plug and one coil at first.

So you ended up changing all coils and plugs?
