So my O2 sensor got damaged, the coupling broke. So Imma remove it and try to solder the connection back. I might need to like drive down to a store or if I cant fix it order a new one.

Will there be any harm driving without it there? having a small hole open? I dont think I can plug it with anything as any tape will burn in.

 

driving it to the store without a rear O2 sensor shouldn't hurt anything. You may cause the check engine light to come on but as long as you're not riding it hard you should be fine.
