Recently changed all the fluids in my 2008 3500 LMM 6.6

Customer Question
duramax. Turned it on and...
Recently changed all the fluids in my 2008 3500 LMM 6.6 duramax. Turned it on and it was hopping at idle and wont go over 50 mph. Ran codes and it showed P0207 (open circuit injector 7), P0206 (open injector injector 6), P0461(I have an aux tank, so my fuel gauge not going down causes this), P0672, and P02E8. Literally just changed all the fluids and washed it. Just drove it all the way from Oklahoma to Florida with zero issues. Than serviced it, and now this. Need help with fixing it ASAP. Motor has 127,000. Possibly could be bad connectors/wiring to those two injectors.

Okay I figured as much. I just ordered a new set of injector connectors. I will replace 6 and 7 on Monday when they come in. Will give you an update then.
