Has anyone had problems with after-market 02 Sensors for the 99 Lexus ES300. I have changed the one on the front of the moter near radiator at least 6-8 times with 3 diff ones. Still code 1133
Code P1133 has been coming back for over 6 months now. I purchased what they told me was an OEM 02 Sensor. I have 3 total for the one that is at the front of the motor near radiator, in exhaust pipe. When I go back to the original sensor, the car runs rough, and codes rather quickly. I've heard I should by the Bosch 02 sensor, or get one from Toyota. Any help would be appreciated immensely.
