2000 Chrysler 300m with 80,000kms. Ok I resently bought this car and when I was driving it home after buying it the check engine light came on. So I looked and it was giving me the code P0134 which is a Right upstream O2 Sensor error. So I took it to a mechanic and he recomended changing out the old O2 sensor. So I got him to do it, and clear the code. Not an hour after it came back on with the same P0134 code. Is there a fix to this because I have heard of a few 300m's to do this. It runs fine, no rough idle or anything. Just can't stand to see that engine light and code on.
