When you gas up your Contour, do you shut it off before taking the cap off? I don't, because I feel it's hard on the timing belt to restart after something like gassing up. I heard though you can throw a code by leaving the motor running while the ca is off. Also, how do timing belts last so long. I mean pulling all that force for 60,000 miles plus. It's amazing how they hold up as long as they do.
