1) See post by Dean linked below.
Note part about not throwing parts at the problem.
2) The sensor before the cat is not affected by the converter. It is the sensor AFTER the cat converter that is used to monitor the emissions. Read the following explanation:
>>>On 1996 and newer vehicles with OBD2 (On Board Diagnostics II), there is also one or more additional O2 sensors mounted after the catalytic converter to monitor the efficiency of the converter.<<<
from this article: http://www.autotap.com/oxygensensors/ppc_oxygen_sensors.html
3) Cat converters don't just go bad by themselves at 84k miles, if it really has stopped working, there must be a reason. If you really DO need a new one, check into aftermarket cat converters, the oem one is pricey.
