A failing catalytic converter can turn on the check engine light, hurt performance and keep your car from passing smog. We test first to confirm the converter is really the problem and not a sensor or fuel mixture issue. When replacement is needed, we install the right unit and check the fuel trim, misfires, leaks and temperatures that can shorten its life.

When you may need this service

  • The check engine light is on
  • Poor performance
  • A failed smog test
