Just a follow up to this thread. When I put on my plug wires I ran them neatly parallel as evidenced here.



What I have since learned is that the wires for cylinders 1 & 3, and 5 & 6 should not be run closely together. Induction "cross fire) can occur. I was experiencing random misses and they seem to have gone away since re-routing the wires according to this ford TSB image below. It says 5.0L but it applies to the 5.8L as well.



Also, "Spark plug & coil wires should measure ~7KOhm/foot from the terminal inside the distributor cap to the terminal in the boot that slips over the spark plug. "
