I got my car serviced and they told me I had a bad Catalytic converter. It caused my check engine light to come on. I have an 04 Cavalier, and it would be very expensive to fix. Do I need to replace it? Will it cause me problems on my car? My car seems to be getting less gas mileage, and my engine light is still on. Otherwise my car runs just normal.
