alright so i just need someone to double check and see if im right here. im throwing 2 codes after replacing my headers / dp with hi-flow
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank)
P0420 Catalyst System Efficiency Below Threshold (Bank 1)
now im pretty sure p0420 is because the new cat is flowing more then the stock cat, which would throw that code.
for P1133 if im reading it right (and according to my wideband) the computer isnt sweeping like it should be to get stoich (14.6) AFR. and bank 1 sensor 1 is the first O2 right? so my guess would be in open loop mode the O2 cant sweep (bad sensor?) and either goes to lean or to rich during idle (which shows on my wideband because its either in the 13's stuck at 14.1-14.4, or goes up to 15, 16 which is lean)
can anyone of the techs correct me if im wrong?
