The V-10 has the older OBD-II emission compliance regulations attached to it so you may not get a CEL whenever there is a skip. I pulled a 10k camper 125 miles on 9 cyl's and never got the light. (2001 F-350)
I also have a 2006 F-350 dually that also has OBD-II on it. Never get a CEL when I fuel with the engine running, nor did I get a light when it started cutting up last month because of a burned plug.
The V-10 is catagorized as a 'heavy duty' engine so the emissions compliance is much less than a F-150 or a car.
