I thought my misfortune may help someone. I started this thread about code P2149 (https://www.dieselbombers.com/5-9-li...834-p2149.html). I got the code again only this time it came up with injector #6 error as well. I ended up having my injectors replaced, but some of the hold down bolts were very loose. I don't know if anyone else had this issue when replacing injectors, but the shop said it may have been my problem all along. I currently have 112k on the truck. If you are getting any injector codes it may be good to take the valve cover and exhaust rockers off to check the injector hold down bolts. They are only supposed to be torqued to 8ft/lbs from what I can find so I will check them again after 30k or so and post if they are loose.
