rpinson

I'm fairly certain that it's the o2 sensor, but I just wanted to see if anyone else had this problem as well. I was driving home the other day in the rain and noticed a bit of a lack of power and just a generally change in the tone of the exhaust then the next morning I got this code. No P0300, No P0171. Only the pass side. Seems like the sensor may have gotten wet and shorted, right? I haven't been able to get under the car yet...anything else I should check?
