Cummins Turbo by jarhead1969

I recently got a smokin deal on a 07 dodge dually. Had to have the Turbo replaced due to carbon build up. Dodge told me to take it out on the road once a week and run it above 50mph and 2100 rpms for 20 minutes to clean out. I'm not sure I buy this approach. any idea's. I love this truck, but I'm seriously reconsidering the purchase and may sale it

The dealer advice is essentially correct. I've owned Cummins-powered Rams for over 13 years now, and they can get iffy if they don't work for a living. Remember, this is a medium-duty engine that's available in trucks all the way to class 7 (GVWR up to 65,000 pounds). If you don't load it with either regular highway speeds or substantial cargo weight, you will develop buildup in the engine and turbo. I give my 2005 Ram dually a few good romps every month.

Malfunction Indicator Light keeps coming on by ehestdalen

I have a 2008 Ram 2500 6.7 diesel with 60,000 km and about a month ago the Malfunction Indicator Light would come on for a day or so then go off for several days, then it would start all over. I took it into the dealer and they said the fault code for the light indicated that the turbo was losing pressure so they changed the turbo (warranty). Now the light does the same thing but more often, the dealer latest theory is that it is a BS code and has no reason, a clinch in the computer, so they ran a flash program, it still does the same thing, light on for a day, then off..... Has anyone had the same experience and what was the outcome?
 
Thanks..........ehestdalen

I talked to Mechanic Friend and sounds like the EVR valve is the issue. He had the same issue and ended up replacing that piece

Not sure what transfercase is in your truck, but unless you forced the shift lever, chances are the axles may have a disengage vacuum on it and may be your problem. On older cases the shift forks bend or wear out, usually from lack of oil, so good luck.

first of all don't even believe that in truck milage meter, it's crap. Test your milage by dividing the miles driven by the fuel used. My 04 gets terrible milage. Wish I knew how to improve it.

My first question would be how you know that the wire from the fuse to the trailer plug is ok? There is a fuse to each side in the fuse box. Check ton make sure it has power on both sides.
