If you have average mileage on it, you should go get it checked. That is too low for an idle. The vibration is probly from the low idle.
a dirty air filter or a dirty fuel filter will cause a diesel to smoke
why is my 1990 305 gmc idling rough when on the gas peddle runs great
The engine hourmeter on the Silverado/Sierra pickups will give the total run time of the engine including idling time. There is no direct correlation to the milage showing on the odometer. The comparisons you can make is if the hours are extremely high and the milage is low then you can assume that the engine has been idling alot. Alternately, if the hours are low and the milage is high then you can assume that the vehicle has a lot of highway miles on it.
Sierra, since its a name and thus a proper noun it should start with a capital letter.
