    No temp fix that I know of. It just causes your car to run rich all the time if your running stock ecu. Cheapest place to order the part IMO is subarugenuineparts.com. OEM P/N is 22641AA042.

    I am now getting the same problem with my car, but the trouble coming up is just telling the car is rich not that the o2 sensor is bad.

    The code is just telling me the car is running rich, not getting anything else from it
