My buddys 06 2500 6 speed rpm guage sticks around 200 and won't really move depends how fast your going what could it be thanks
did the same thing last week... total bill was for $950 dollars and they have to flash it with starscan.. at 125hr...I have the same problem, and its my "instrument cluster". $440 dollar entire dash panel/gauge replacement that has to be done by the dealer because they have to program it with my correct mileage. OUCH. At least my bad injector is covered.....
