Engine diagnostics serve to keep your engine running more efficiently. We are capable of detecting malfunctions that cause severe damage. You should have engine diagnostics performed when the “check engine” light comes on.

Engine diagnostics will help detect problems early so that minor problems never become major problems in the future. We also run engine diagnostics to help keep emissions low. Sometime if the engine is malfunctioning, your vehicle might not pass an emissions test. If your “check engine” light turns on, call us to set up an engine diagnostics service. Our experienced staff will work hard to get your engine working to get you rolling down the road.
