I don't know much about cars but my husbands had 2 o2 sensors. He had changed one and it still ran like crap. The shop changed the other and it ran great.

The 02 sensor went bad on my car also, my husband took it to the shop and had it changed, it lasted less than 10 miles. It was replaced again, and we have had 2 different shops check it out, and it isn't idling correct either. But to get a correct diagnostic, you have to take the battery cables off and replace them to erase the old codes, that were in there when the sensor went bad. Auto Zone, if you have one near you, will check the codes for you for free, but until you unhook the battery cables and rehook them, it will still show the 02 sensor bad. The mechanic that replaced the 02 sensor, said that he had gotten some bad ones from the part store that he buys from. Probably made in China!
