Check Engine Light Diagnostics in Lake County, IL

A parts store code reader tells you a code. It doesn't tell you why. Dave tests the actual problem so you replace the right part the first time.

What the diagnostic includes

  • Full scan of engine and system codes
  • Live data and hands on testing
  • A clear explanation of what's wrong
  • An upfront quote for the repair

Pricing

Questions

Can I keep driving with the light on?

If it is flashing, stop driving and call. A flashing light usually means a misfire that can damage the catalytic converter. A steady light is less urgent, but get it checked soon.

Do you come to me for a diagnostic?

Yes. We diagnose most cars right in your driveway or parking spot.
