I saved my old injectors as well, he swapped them out for me and I sold them locally for the same price as I bought the Rockauto ones to recoup my costs. On the wild chance you can work something out at the dealership, maybe you can do the same or you can ship your defective ones to me, I'll swap them with my buddy and mail them back to you.
How'd they test the injectors to verify which ones failed, etc? I was getting black peppering all over the backend then eventually I couldn't even get the truck to run when my index 7's failed. I've got no codes, just the nagging and random reduced power warning that I'm hoping will go away when I finally swap out the CCV and vacuum lines.

I appreciate that. I may try to return them under warranty first and see what happens. I guess these were throwing codes, they said that they tested the flow somehow. Don't ask me how.
Can you check with your mechanic buddy if he knows how they do the injectors? Do they only replace old index ones or all? I suppose that's probably up to the SA.
