Check Engine Light on. Checked code... it's p0420 - Catalytic converter. Replaced PCV valve and light is still on. Mechanic checked engine, spark plugs, and oxygen sensors. Believes that converter is simply failed because my car is 16 years old. Otherwise in great condition.

    Catalytic converters do wear and start plugging up and restricting exhaust flow. Back pressure will build till you feel loss of power and rough running. O2 sensors will start tripping as well as PCV and EGR codes. 16 years is definetly a long time for a cat. converter.
