Default Changing injectors on a LB7

Hi Guys, I am new to this sight, I had my LB7 for a couple month now, I love the truck. I was doing some reading on here and see everyone talking about the injectors going out. I was wondering if any one has any Details on changing them. I talked to a local garage and he said it would cost $3500 with parts and its a 12 hour job. I think for that kinda cash I would tackle it myself if they go out. Just wondering if anyone has any details on this job. Talk to you all soon, Later SnoMan

So far so good on the injectors I have a 112k on the truck and I checked the warrenty if the injectors were changed and the dealer said they are the original ones so??? Hopefully I have good luck with them for a couple thousand miles. I will let you know if I have any questions if they go out on me 2500HD. Thanks again

some people never have a problem with them.

mine had gone out the first time at 115k and it was replaced under warranty.

i just replaced all 8 at 140k cause i had a few of them actin up and fwiw doing all 8 would save me some headaches
