If you have a big truck instead of a little car such as my dads Honda crx, the shape of it creates wind resistance so your engine has to work harder to fight the wing. Basically you get less gas milage not that trucks get good gas milage anyways.

How do you tell if the hours on motor match mileagehave a 2005 sierra pu?
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.

Yes. A coil pack controls the power going to it's attached spark plug in your engine. If the pack is weak, your engine may not get the spark it needs to ignite the air/fuel mixture. This can cause loss of power, poor fuel milage, or the vehicle not to start at all.
