is your car running very rich? I had my front o2 sensor go out.. cant remember if it was p0138 or p0131. The car was getting 4-6mpg.. just dumping fuel.. spark plugs were black.. its steadily will keep getting worse. If your car is feeling sluggish you may want to consider replacing your front o2 sensor.
