Don't we have 2 plugs per cylinder? Could it be that there was no code because 1 spark was enough to keep all the readings in range? Now if it was both plugs on 1 I would expect a code.

Well there are 16 plugs, but there are only 8 coils and 8 wires going to those coils. Each coil sits on one plug and then has a little wire that goes off to the other plug. I can't really tell from the pics which wires these are. If it was one of the "main" wires then it makes no sense that the truck is still running right, but if it was one of the little jumpers from the coil to the 2nd plug I could see that. We need one of the techs on here to weigh in on the matter.
