I have the same problem. Injectors and coilpacks are not under the powertrain warranty either. I was charged $180 diagnostic fee and the tech had no idea what was wrong. I swapped injector 1 and 2 later that day and figured it out in 15 minutes. I get a CEL about it everything 7k miles or so. I'm wondering if a good cleaning @ Witchhunter would fix it.
enough zip ties and duct tape will fix anything.
