May check the harness. Thought i had injector failure, ended up being frayed wires on the injector harness (this was in 2010 at 50k miles). There is a service bulletin about it

The injector harness is a common problem on that version of the engine. Apparently, someone at GM forgot to make sure the wiring harness wasn't allowed to rub on a sharp edge. From what I gather, this isn't a "some of them are rubbing" type of deal, this is an "all of them are rubbing" situation.
