Code P1133 and P0171 for Lexus RX 300
Hi,
I have a 1999 Lexus RX 300. I am getting the two codes P0171 and P1133. I took it to the dealership and they told me that it was the MAF sensor. I changed that and the Check engine light still came back on. I took it back to them again and this time they told me that it was my O2 sensores. I have replaced both the bank 1 O2 sensors on my car but the check engine light came back again with the two codes mentioned above. I am getting tired of paying the delaer ship fee for the incorrect diagnosis. Can anyone help in identifying what else could be causing this problem. Thanks.

You can either buy the code reader or go to Auto-zone who will read the codes for you for free.

Welcome to the Club.
As Salim mentioned, you can go to AutoZone and get the codes read for free as I'd be interested to know what the last set of codes were. A P0171 can suggest a MAF, but usually getting the P1133 can suggest and A/F sensor.
What I'd be interested to know is if the codes you are getting have a p/d (or pending) by them.
