Don’t Ignore That Warning Light — We’ll Find and Fix the Problem

When your check engine light turns on, it’s your car’s way of telling you something’s wrong — but it doesn’t tell you what. That’s where we come in. At 1st Performance Automotive, we offer professional engine diagnostics in Apopka, FL, to quickly pinpoint issues and recommend the right solution.



Whether it’s a loose gas cap, a faulty sensor, or a deeper engine issue, our ASE-certified technicians use advanced diagnostic tools to find the problem and get you back on the road — without unnecessary repairs or guesswork.


What Is Engine Diagnostics?

Modern vehicles rely on onboard computers that monitor your engine’s performance. When something’s off, the system stores trouble codes that indicate what’s wrong. Our diagnostic process involves:

  • Connecting a professional scan tool

  • Retrieving diagnostic trouble codes (DTCs)

  • Interpreting the codes using manufacturer-specific data

  • Performing system tests and visual inspections

  • Recommending the correct repair based on evidence

It’s not just about reading a code — it’s about understanding what it means and how to fix it properly.
