Thanks again, Robert. I can fly the hair off of a $19million Army helicopter but I truly know very little about diesels, much less the Duramax. If you've time, I'd appreciate your thoughts on my questions below:
Is this an issue that should be checked out by a GMC dealership service dept?
Why is there no other "noticeable" in how my truck runs?
As there is no noticeable difference to me, am I hurting the truck by running it?
If it is the injectors, do I change all of them? Just that one? Just one bank/side?
And....should the injectors be replaced with factory or do you recommend and "upgrade"?
