I am having a problem with "rich" exhaust and a rattling catalytic converter. I assume the internals of the cat are shot due to the internal noise. My question is concerning the o2 sensors and the rich exhust fumes: Do I need to replace the sensors or will a new cat solve this problem. As soon as the cat started to rattle the rich fumes began to be noticiable. I don't have access to a diag. code tool. Any suggestions? I plan to replace the cat myself. s70 w/130,000
