How do I get to cylinder 8 sparkplug? Ive changed out all the other ones but cant get to this one. Any ideas or suggestions? Its a foulled plug and throwing missfire codes. I pulled the boot off and no change in idle still ruff. So I narrowed it down to this one. It's on the passenger side. Any help is appreciated.

Leave fuel rail in place.

I just pulled the fuel lines. Took about 20 minutes. Made life soooo much easier.

I was gunna do that at a last resort. Last time I did it on my old 89 F-150 5.0 I bent the fuel rails and one injector was corodded into the fuel rail.

Only cylinder I had an issue with was #7, the fuel regulator was right above the COP securing bolt, real pain to get to if the rail is attached. Can be done (did it the first time) but much easier to remove the fuel rail IMO for that one.

Mine dont have COPs it has two 4 bank coils.

I attach a swivel joint to my plug socket and then use a long extension. Works great every time for removal and torqueing down the new plug.
