I need to replace the oxygen sensor 02. I know it is on the drivers side on the manifold. How hard is it a job and can a novice replace it? Explain how please

Not too hard, requires either a 7/8 end wrench or an o2 sensor socket. Just remove old one and install new one, plug it in. Yo u may have to have the check engine light cleared with a scanner
