Re: Duramax towing “engine reduce power”
Does it give any DTC codes? Mine did it and I would get "low pan rail pressure". I tried everything, lift pump, relief valve. The only thing that fixed it was replacing the injectors. I know that's not what you wanted to hear but I fought it for awhile before replacing the injectors.
