"Service Engine Soon" light & fault code
Greetings all.
About a week ago, "Service Engine Soon" light comes on; @ my local service center (not a diesel shop), the fault code indicates "misfire on #4".
It was reset and remains so for about a week. Just reappeared.
Worrisome?
Solutions?

Wild Bill, thank you.
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 really appreciate your thoughts on my questions below:
Is this an issue that should be checked out by a GMC dealership service dept or should I look for a recommended non-dealership shop?
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"?
