hard to drive and codes Camaro 2002 SS A4 , car stock only LT headers and K&N Cold Air Intakes
since i bought car i had these codes and it was driving fine
p0140 o2 sensor no activity detected bank 1 sensor 2
p0160 o2 sensor no activity detected bank 2 sensor 2
p0405 Exhaust Gas Recirculation (EGR) Position Sensor Circuit Low Voltage
p0412 Secondary Air Injection (AIR) Solenoid Relay Control Circuit Bank 1
p0418 Secondary Air Injection (AIR) Pump Relay Control Circuit Bank 1
all above is removed from car but not codes toned/removed and weird code for egr while that car model shouldnt had it.
and now those 3 came up lately
P0481 Cooling Fan Relay 2 Control Circuit << mostly come up when A/C on
P1133
p1153
changed Front O2 denso , p1153 gone but sometimes show up but p1133 still comes up after driving for while
now if i need to drive it kinda normal , but still not as it was i had to clear codes with obdll
if i hit WOT shifting takes time and sometimes missfire p0300
sparks/wires and fuel filter replaced, cleaned injectors and still same.

Your best bet is to find someone with HPTuners to disable EGR/AIR and the downstream O2 sensors. Not just clear the codes, but disable the codes and turn off anything related to the hardware on these so the PCM ignores them completely.
From there they can see what the O2 sensors are reading, manually control the fan to see if there are any issues, etc.
