My engine light is on and I need to replace my oxygen sensor. Has anyone changed theirs? Is it a screw on one or do I need to have it professionally replaced? Thanks.

They all screw in.

You will need a "crows foot" to get to it especially the front one. I can't remember exactly but I think it is a 7/8ths.
