I recently got the P0031 CEL code on my car and most probably i'll need a new O2 sensor.
Is there a possibility that the CEL was caused by a bad batch of gas and i could spare my O2 sensor? How long could i run the car with a faulty O2 sensor without problems? Will there be any side-effects?
Does anyone know if the front O2 sensor for the USDM Legacy GT is the same/or will work on a JDM Legacy GT (2004 model, EJ20 Engine) ?
Because the quote that JapanParts gives me for the JDM O2 sensor is bloody insane....
Thanks a million!!
