i replaced rear O2 sensor, now have P0430 code....
it seems that by replacing only the right rear O2 sensor (its heater was dead and it was throwing P1193, IIRC), the front sensor may not be working quite well enough, thus the P0430 code (bank 2 cat converter working below efficiency threshold).
my theory is that i may be able to swap the new sensor to the front, and vice versa, and it MIGHT fix the problem. perhaps the old sensor is not quite up to snuff and thus the engine is running a bit rich on that bank which the new sensor is picking up.
