I don't give a crap about "nice and tidy". That was not what I asked you. I asked if the plug wires were routed EXACTLY like the factory service manual illustrates.
"No crossing wires"? That may be part of the problem. Running wires parallel to each other invites cross-fire, and that's especially dangerous on #5--#7.

Any decent scan tool can record a "movie" on a vehicle, going back to the beginning of computer control in 1980 1/2.
Yes, I understand that you haven't found the problem yet, and you're frustrated.
