Re: 93yj failing
The root cause of the failure is the fact that the engine is running too
rich, and I absolutely suspect that the exhaust leak before the O2 sensor is the fault. Make that leak go away. Don't replace the catalytic converter. Although a fresh one will, in fact, clean up the exhaust, it won't survive to next year's inspection, as the rich mixture will destroy it. Fix the root cause, not the symptom. Jerry "L.W.
