An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

A little while after I bought my 2001 Lincoln LS V8 (purchased it in 2008)I had to replace the Catalytic Converter, O2 sensors and pvc valve. It was losing power and would not pass smog. Check engine light had been on until I fixed these problems. These items are just a few of the things I have had to replace on this car.
catalytic converter red hot and no power
runs rich and it wont pass smog plus it check engine lite comes on
