The 2004 Silverado 2500HD LLY Duramax threw codes P0202 and P2149 yesterday, which means that the wiring to injector #2 is shot. It will sporadically run like normal, but it's time to replace the connector. I took a quick video of it unplugged, so you can hear how awful it sounds. The fix is to wire in a new connector, which you can find online for about $30. I wired in the new connector after shooting the video, and it runs as good as new.
