IF all are high its the cat. If its rich ussually its the 02 sensor. If lean its an air leak after the AMM. Check the plastic tube from the AMM to the throttle body and check for injector leaks. Lots of info on that in the FAQ.

could be your catalytic converter. Otherwise I am clueless to what it could be. If all else fails move to NC, starting next year only 95 and later will need emissions test.
