Why does my catalytic converter not work?
If your catalytic converter has become badly clogged, then it may no longer be able to push out exhaust at the same volume that it used to when it was functioning properly. Because of this the exhaust will push back into your engine, potentially throwing off your air fuel ratio and the whole combustion reaction in your engine which affects mileage. This will cause a problem with how your engine is burning gasoline, and the result will be that you're going to be having to head to the pumps to fill up on gas far more often than you used to.
How to tell if a catalytic converter is bad?
The sounds your car makes are some of the best tools you have for diagnosing problems.

The catalytic converter includes the catalyst metal, which is platinum or palladium as we've said, but there's also generally some kind of a honeycomb pattern of ceramic or other material inside the converter as well.
