    Check engine light came on while driving--took to dealership and was told the catalytic converter needed replaced for around $950

    Car runs fine but the "service engine soon" light came on that the repair shop said the codes showed a bad CC. We hope that's all that is wrong!

    Had a fuel system cleaning done which set the check engine light off. Turned out to be the front catalytic converter for precisely the reason stated. Fixed through replacement.
