Check Engine Light & Engine Diagnostics

Check-engine light on? A code reader at the parts store tells you a light is on, not why. We diagnose the actual cause so you are not throwing parts at it. Note: Michigan has no state emissions test, so this is about fixing the problem, not passing a check.

What this covers

The work, spelled out

  • Full check-engine-light diagnosis with real scan tools
  • Sensor, O2, and emissions-component testing
  • Misfire, rough-idle, and stalling diagnosis
  • Fuel system diagnosis
  • Clear explanation of what is actually wrong
  • A quote to fix it, not a guess

How it goes

  1. 1

    We read the codes

    Professional scan tools, live data, the whole picture, not just the light.

  2. 2

    We find the real cause

    A code points to a system, not always the broken part. We test to confirm before recommending anything.

  3. 3

    You get a plain answer

    We tell you what is wrong in words that make sense, and what it costs to fix.

  4. 4

    Fixed and verified

    We repair it, clear the code, and confirm the light stays off before you leave.
