same as this post! 300, 302 303

Last time scanned i picked up an 02 sensor code too. replaced sensor not more more then a month and a half ago. Im sure you guys are on the right path with a relearn procedure but how do you do it? the dealer i took mine too was dumbfounded. I continue to keep driving it because it runs perfect. I just hate cel flashing at me and i think im gettting a poor fuel econ too. Bout to take the cel bulb out or put some tape over it. I have 190k on the aveo and about 20k on the 07 motor<
