You need a new o2 sensor...Bank 1 Sensor 2...not sure but I 'think' this is the rear o2 sensor

While these codes are most likely the O2 sensor, I was getting some of the same codes and it was MAF - apparently the MAF wasn't far enough out of spec to throw a MAF code, but was screwing up the A/F ratio enough to throw a code downstream at the O2 sensor. So... if you've got new O2 sensors, I'd look at the MAF.

I replaced my MAF about a Year ago lol :mad:

According to Bentley on CD its the O2 sensor behind the catalytic converter. The new Bentley CD won't allow cut and paste, what a bummer.
