A low oil pressure reading when idling for a 1986 Fiero is normal. As long as the oil pressure goes back to normal when the car is being driven, there should be no problem. If it is not, then the oil pressure sensor or the oil sending unit should be looked at.
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.
