| Diesel Engine problems |
Truck lost almost all power and barley moved itself from the travel lanes to the side of the road, had to be towed and after a week in the shop! at my business loss . A crank sensor was determined to be faulty,then an e. G. R valve and finally replaced the p. C. M. Check engine light still on and off and still weak on power. Fuel usage is horrible most of the time 6 -7 mpg. Truck currently towed to another dealer for a transmission problem, it wont move!! I found trans to be almost out of fluid. I check fluids regularly. Truck has 16k on it now. And this is the second tow, the first at 2,000 miles.
