Disappears deep under plenum. My best guess....the #6 spot.

I have no spark on six. Plug is carboned up. Marc suggested to use volt meter to check continuity between wire pairs to rule out bad wire verses pack. I hope its bad wire because I can change it without plenum removal.

Change plugs on number 6 plug wire....using good plug. You can change a plug wire without removing plenum??
![]() 1 and 6 fire with 1 TDC compression and 6 TDC exhaust. 8 and 5 fire with 8 TDC compression and 5 TDC exhaust. 4 and 7 fire with 4 TDC compression and 7 TDC exhaust. 3 and 2 fire with 3 TDC compression and 2 TDC exhaust. Then we get to 1 and 6 again but this time 6 is TDC compression. Drivers side bank from front to rear: 1 3 5 7 Passenger side bank from front to rear: 2 4 6 8 Firing order is 1-8-4-3-6-5-7-2 ![]()

Ok I was right about cylinder numbers. Definitely #6 wire in #2 spot. Any harm in leaving it there?

I think the story goes that the cylinder under compression would fire and the other one would be wasted spark. Yes - No?
