Help

I know this is stupid but I can't seem to remember the firing order on a 5.4. I got a cel that says COP 5 is bad but not sure which one that is. Thanks for the help.

Well, it's not the firing order, but the cylinder numbering is

Firewall
---
4 8
3 7
2 6
1 5

Radiator

If you got a P0305, then your driver's side front most cylinder is the location of the misfire.
