Guys, I have a 2000 F-150 (normal gas engine) that I am trying to find the SP firing order on. I was having some problems with the truck (PO303 misfire detected)running rough and replaced the plugs. It ran great for two weeks but itis running rough again.Hooked it up and it reads PO307 cylinder 7 misfire detected.

 

4.6L and 5.4L firing order is 1-3-7-2-6-5-4-8
