If you are new, then  first you got to suckle your Momma and be potty trained, next you go to kindergarten through 8th grade and learn to fix a go kart, next you go to high school and learn to fix your first beater. Next you knock up the GF in the Beater's back seat and got to get married. Next thing you know you go to trade school for auto repair to be able to fix your Mini van the wife hauls your Hot N Tots around in.

 next thing you know you got to buy a Scan tool. The End:-))
