Muliple Codes

[annekolar@hotmail.com]

:cries: The check engine light in my 1999 RX300 indicated (Auto Zone analysis) a code P1150. We changed the O2 sensor. The light came back on. The confusing part is everytime we go back to the Auto Zone for an analysis the codes keep changing. First we got P0125. We also got P1135 which cleared but P1150 is back with P0125!!! Any suggestions?????????????

Are you using OEM sensors? I have read multiple times about the RX having problems with aftermarket sensors. Do a search here for more info.
