So, I've been reading about spark plug wire routing as a check for intermittent missing. I have searched high and low and am unable to find the wire routing diagram for the '97 460. Hopefully someone here has one as I am having some symptoms. I don't know if they are related to the wiring but here are some symptoms I have been having:
1. Not all the time but occasionally it will crank for 4-5 seconds before starting, other times it starts immediately. And it does it when it is cold or at temp. Also, and only occasionally, when it starts it sputters for a few seconds and then idles at normal RPM smoothly.
2. Occasionally when stopped at a light or waiting in gear it will sputter like it wants to die but comes back to normal RPM.
My manual shows the firing order for a 7.5L engine is 1-5-4-2-6-3-7-8. I suggest you keep the wires for 4&2 as well as 7&8 as far apart as possible. This will help prevent cross-fire like the routing illustrated in the photo you posted for the 5.0L engine,
