Looking for an auto mechanic is kind of like looking for a pediatrician and a babysitter rolled into one. You wouldn’t entrust your bundle of joy to anybody but the best. In your vehicle’s case, finding an honest and qualified mechanic will save you time and money, not to mention a whole lot of anxiety. Trent Hamm, a contributing writer for The Simple Dollar, knows this all too well.
Your vehicle may be working fine, but that doesn’t always mean you can hit the road safely and expect no problems. Some issues, such as a bad catalytic converter or knock sensor circuit malfunction, may not reveal themselves until you’re already miles away from the nearest repair shop. This is why cars come equipped with onboard diagnostics (OBD) systems, which detect powertrain problems that affect emission.
