I suspect your engine management computer has detected something out of whack and continuing to run the engine may ruin it. I would check the oil and coolant levels. See if that diesel's catalytic is overdue to be serviced. The "five minutes idle to shut down" timer might be wrong. Turn on the cruise control and set it while idling. Just guessing. Get dealer to scan for codes. I was lucky to retire before all these computerized trucks hit the road.

That's a $10,000 engine so it may be a good idea to have the dealer scan for codes and look things over. It may be something simple to fix. It's an awful feeling to own/drive a truck you can't trust to get you home without an expensive breakdown and repair.


Every time I go up a hill my check engine light come on
