Yup, that is an odd one--

Here, from the shop manual, are all the possible causes--work the list...
  • Contaminated HO2S sensor.
  • Exhaust leaks.
  • Shorted /open wiring.
  • Improper fueling.
  • MAF sensor.
  • Deteriorating HO2S sensor.
  • Inlet air leaks.

So I changed out the passenger o2 again because of the 0133 I kept throwing. Took off catted mid and put it in all sealed up no leaks. This morning threw 0133 and 0153. It can't be bad o2 sensor. All the wiring looks perfect. I'm going to put the o/r mod back on. Don't know why that would effect it but it's the only thing that was changed
