Re: Ram 2500 shaking while idling
they shake on shutoff is known as the "cummins shake"...its totally normal.
as far as rough idle, does it have a hard time starting? extended crank? try changing your fuel filter, make sure you have some fuel additives. also try turning your key on, key off, and key on again, then leave it on...if there are any codes, it will pop up in the odometer window.
I am going through an all out injector replacement, it isnt pretty....so hopefully thats not whats wrong with yours. also, if you dont find what you need here, or at dodge talk, try dieseltruckresource.com every thing you need and then some...
