Remember when dad or maybe you would lift up the hood and take a look at the points, plugs, rotor and distributor cap? Unless you are driving a car from the 1970’s you know that everything in your car today runs by a computer. Today’s cars have more computer power than the first spacecraft NASA landed on the moon.
When a problem comes up with your car these days there is no guessing about what is wrong. We use computer diagnostics to check your on-board computer and it will give us error codes that we use to determine the exact problem and fix it fast.
