hey, yes i finally got it fixed... i replaced my catalytic converter and both my post cat 02 sensors, bank 1 and bank 2... if i were you, i would take it to a shop and have them test out each and every 02 sensor... they put it on a machine and measure when it turns on and off... and that should tell you which one is malfunctioning... i went crazy with mine... even after i changed my cat, i got a code for the bank 1 post cat 02 sensor, i replaced that right away, and my gas milage shot back up and my check engine light was gone... soo good luck!
