So the other day I was running down the interstate at 70mph pulling the boat. My brand new truck goes into reduced power mode. I pull over and the trucks barely running, and not responding to the pedal when I tried to take back off, like it was out of fuel. Trucks completely stock besides ad 165. Dealer came and got it. went up there the next day and they had it apart, a chunk of metal had found its way into the egr valve and had it wedged open. Just hit 2000mls. Where could it have came from exactly?
