so another problem with the 6.0, I just replaced the injectors and now I'm getting a p0275 and a p0676. I get the 676 is the number 6 glow plug which wasn't an issue before the new injectors and the 275 is a contribution code for cylinder 5. it doesn't feel like it's missing or idling funny and it's not smoking. the batteries and ficm are newer and new hpop. could it be a wiring harness. I think it might have had the cylinder 5 code before the injectors
