Drive it like a hooker - Hard with no guilt - Because the motor can handle anything you throw at it . I dont baby my truck at all and never had a code show in 7K miles. In alaska the fuel will cost you as much as a hooker but you can't put a price on a smile!!!
If you don't want to spend the good money on a programmer you can always go to Shucks or Napa and but a code reader for $50-$100 bucks.
