Cylinder diagram 02 v8 4.6l

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.

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?

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?
