Bocifus:
The problem turned out to be a combination of two things. Cummin's NW found a pack rat had stuffed my filter box with rags, insulation, and a host of other things and it was stuffed full. The other thing was a partially sticking exhaust brake.
The dealer in Cottage Grove claimed to have the best diesel mechanic in the state, but he couldn't solve my problem. He replaced a lift pump that was good and had DC void my warranty, and charged me nearly $600. 00 for it.
I just sued the dealer in small claims court for the cost of replacing a good pump and charging me for it. I won the judgment and just got their check in the mail the other day.
See my post "I WON!"
