o2 code question my car has a "bank 2 low efficient cat" would that be a sensor or the cat?
i was looking at it on the scanner and it just looked like one of the sensors were just responding slow so thats why i think it is just an o2 but my other question is which sensor would that be upstream or downstream?

Sounds like you're throwing a P0430 code? Could be either the rear passenger side 02 or a bad cat (most likely). Bank 1/2 is drivers/passenger side, Sensor 1/2 is precat/postcat.
