Just a thought, I had a similar problem a while back after long tubes p0133 and p0153, changed o2's fronts the back are shut off, No codes, wash the car get a code, clear the codes and drive the car codes do not come back, wash the car couple of weeks later as soon as I fire it up codes again, so has anyone noticed after driving in the rain or washing the car the codes come back,,,, Just a thought because this was my issue.
