These codes are telling you that there is a problem with the ECM harness, targeting the #2 and #7 injectors. It's time for the fix. You can do the ice-pick, but in my opinion, that's only temporary. The kit from the dealer to do it right is around $250. I just had mine done 2 weeks ago.

where did you find info on the harness being cover under warranty? I have an 06 lly completely stock, that is having the same problem and throwing the same codes, but my dealer says only lubricated parts are covered so the wont do it. Thanks in advance for your help.
