Fellas,
same issue here and ive replaced three O2 sensors that through codes all at the same time (impossible). I still get P1129 followed by P0135 and P0155. did the coil packs, spark plugs, air intake sensor, MAP sensor, and as stated the three O2 (bank 1/1 bank 1/2 and bank 2/1) still no dice. any advice? heard on the 4th gen talk it is more than likely a PCM issue and covered under warranty as I have a 2012 with only 52K cause I stay deployed.
