Rx300 misfire
Huge problem, my 1999 lexus rx300 first threw a P1135 following a P0125, I tested the sensor and it was open at the heater circuit then then I was waiting the new part in the mail and during that time it kept running rough and then it threw a P0300, P0301, P0305, P0303. I was thinking that the PCM cannot monitor A/F ratio without the sensor so maybe the injector base pulse width was good enough. The misfire is are on bank 1, same as the bank 1 A/F sensor. What do you guys think?
