We have a team of Automotive Service Excellence (ASE)-Certified technicians who use a combination of state-of-the-art diagnostics equipment and experience to diagnose your problem. Check engine light service can be as simple as tightening a loose gas cap, but some of the more common trouble codes indicate you need to replace spark plugs, a mass airflow sensor, or a catalytic converter.

We work on all vehicle makes and models and offer a 24-month/24,000-mile warranty to give you peace of mind. While we love seeing you in our shop, we’d rather see you on the road.
