Just a small correction, the cateras had their engine designed to run as 2-3 cylinder engines, and the two never cross paths...

Air is sucked in through 2 throttle plates, then into each sides of the engine (I don't count the crossover valves) Then out the exhaust and all the way back to the rear resonator, and even there the gases still have their separate passages....

I think that if you get a sniffer and you hook it up to the one exhaust pipe and then the other, and say the one Converter went bad you should be able to tell the difference...

I still think you have a lean condition in your case... so go to the auto zone and have them scan your car, and see if the coolant temp sensor and the ambien temp is working properly...
