the o2 sensors switch lean rich lean rich and adjust the fuel trim (long term and short term) so bank 2 sensor 1 is the o2 sensor, then the cat, then sensor 2 monitors the catalyst reaction or efficiency. if this don't jive with the computer parameters then a p0430 code is set.

Oh I gotcha!

I use a program that installs into a computer, and connects to the car via usb to OBD 2. You get complete details and live monitors.

After replacing the bank 2 sensor 2 it seems the problem has been fixed a bit, but not by too much.

I was wondering... what should the reading be on the TPS(throttle position sensor) when the intake is closed? I think mine was reading over 20 when my foot was off the gas.
