got a code (p133) for Oxygen sensor bank 1 sensor 1. replaced with bosch O2 sensor. Now the car runs perfectly, all my symptoms are gone; Gas mileage is great, and the readings from the computer show the voltages changing constantly as they should(opposite of what it was like before I replaced it). However, I cleared the codes and drove for about 6 hours, and at the very end the code came back. Though none of the symptoms did. I've seen several other posts about this but none came to any conclusions.
has anybody dealt with this problem successfully? I wouldn't mind so much if I wasn't trying to sell the car...
any help is appreciated,
Thanks!
