Does this component have wires attached to it? Do you have an exhaust leak now that this part is no longer on the car?
Google search -Google images- oxygen sensor Does the part look like any of these images?
if you don't find an answer to your question if you want to take a digital picture and send it to me I will see if I can identify it for you
