I had one code p1128 which turned out to be just one bank replaced @69K. I did replace both at the time. Still think if you are having both P1128/1130 that it may not be O2 sensor. Check after Maf for unmetered air. Those rubber couplers for resonance tube and Throttle body T.
Is the Maf sensor new? Used ones can be a crapshoot.
