Engine Diagnostics and Performance Services

Since 1996, vehicles have been equipped with advanced On-Board Diagnostics (OBD) systems designed to monitor engine performance and detect issues early. At MJB Automotive Inc. in Bay Shore, we specialize in comprehensive engine diagnostics and performance tuning to keep your Volvo or any foreign or domestic vehicle running at its best.

What to Do When Your Check Engine Light Comes On

The check engine light signals potential problems with your vehicle’s ignition, fuel system, emissions, or other critical components. Ignoring this warning can lead to costly repairs or unsafe driving conditions. Our expert technicians use state-of-the-art OBD-II scanners to read Diagnostic Trouble Codes (DTCs)and quickly identify the root cause of the problem.

What Is an Engine Diagnostic Test?

Our advanced diagnostic testing utilizes cutting-edge software and hardware tools to analyze critical engine systems, including:

  • Engine performance and misfires
  • Transmission condition
  • Exhaust system and emissions control
  • Fuel injectors and delivery
  • Airflow and cooling systems
  • Ignition coils and throttle control

Diagnostic trouble codes highlight malfunctioning parts, but our certified technicians apply their expertise to pinpoint exact causes and recommend effective repairs.

Benefits of Regular Engine Diagnostic Testing

Regular diagnostics help catch issues early, preventing breakdowns and expensive repairs. Early detection improves safety, fuel efficiency, and overall vehicle reliability. We also review manufacturer alerts and stored vehicle history for a thorough health check.

How Often Should You Get an Engine Diagnostic?

Don’t wait for the check engine light to come on. If you notice unusual sounds, reduced performance, or vibrations, schedule a diagnostic test promptly. Experts recommend an engine diagnostic at least once a year or before purchasing a used car to ensure you avoid hidden problems.
