133 is the same code I got when my top o2 sensor was bad. Got one from www.oxygensensors.com and the code went bye-bye.



Remember he has an OBD-I ECU. OBD-II names that code as the O2 sensor going bad.

Looking at the first page then going to the OBD-I codes, you are correct, there is no 133. Is it possible that he did the test while the car was running?? Diagnostic checking should be done with the car off as you may get some erroneous codes.

Keep looking keep fighting, you will fix it.
