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 MB Automotive Inc. in Bay Shore, we provide comprehensive engine diagnostics and performance services to help keep foreign, and domestic vehicles running at their best.
What to Do When Your Check Engine Light Comes On
The check engine light can indicate potential issues with your vehicle’s ignition system, fuel system, emissions components, or other critical systems. Ignoring this warning may lead to more expensive repairs or unsafe driving conditions.
Our expert technicians use advanced OBD-II scanners to read Diagnostic Trouble Codes (DTCs) and identify the source of the problem quickly and accurately.


What Is an Engine Diagnostic Test?
Our advanced diagnostic testing uses specialized software and equipment to analyze important engine systems, including:
- Engine performance and misfires
- Transmission condition
- Exhaust system and emissions controls
- Fuel injectors and fuel delivery
- Airflow and cooling systems
- Ignition coils and throttle control
Diagnostic trouble codes help identify potential issues, but our technicians use their experience and testing methods to determine the actual cause and recommend the right repair solution.
Benefits of Regular Engine Diagnostic Testing
Regular diagnostics help identify problems early, reducing the risk of breakdowns and costly repairs. Early detection can improve:
- Vehicle safety
- Fuel efficiency
- Engine performance
- Overall reliability
We also review manufacturer alerts and stored vehicle data to provide a more complete assessment of your vehicle’s condition.

How Often Should You Get an Engine Diagnostic?
You don’t need to wait for the check engine light to schedule a diagnostic inspection. If you notice unusual noises, reduced performance, rough running, or vibrations, it’s best to have your vehicle checked promptly.
Experts recommend an engine diagnostic test at least once a year or before purchasing a used vehicle to help uncover potential issues before they become major problems.
