I threw my first code today. The Mrs. and I went to dinner, and as we pulled up my truck started to sputter a little. Once I parked it I realized that it sounded and felt like it was missing. I revved it a couple times and it eventually went back to it's normal idle.
After dinner we hopped in and she fired right up. Halfway home I realized the check engine light was on. When we got home I pulled a P0273 #5 injector code (thanks to a very cool neighbor who is a mechanic).
I've been reading up on this issue and the best info I've found is in this thread battery light and #5 injector - Diesel Forum - TheDieselStop.com
The only problem is that without more specific info, this is kinda like a second language to me. I'm mechanically inclined, and am a low voltage technician by trade, but I am having a hard time determining which wire is which without any diagrams or pictures.
I fired up the truck again and wiggled each of the plugs that go into the passanger side valve cover, but could not duplicate the misfire I had experienced earlier. Which one of the plugs would be for injector #5? Is it closest to the firewall, bumper or one of the two in between?
My truck is a 2004 6.0L with a little more than 60,000 miles. According to the OASIS report the only issues it has had was...I believe it was an IDM/FICM issue that was replaced under warranty just last year. The original warranty has expired, and while the truck has obviously been well used, it appears to have been maintained well. No egr issues, and runs strong. If it matters, it is a CC LB FX4, and besides the lift kit the truck is otherwise stock.
I'd greatly appreciate any guidance in troubleshooting the issue. I'm hoping it's just a bad wiring harness and that I don't have to replace my injectors. Just in case, what is the average going rate for replacing injectors? I'm not equipped to do this at home so I'll probably have to pay someone.
