oxygen sensor replacement
 

Hi,

I need to replace the oxygen sensor of my 82 280zx n/a but I am having a hard time taking it off. I can't get a good grip on it with the wrench. Is there a special tool that I need to use or special way that I need to follow to take it off?

I appreciate your help.

Thanks

Did you try coming at it from underneath the car with a long wrentch to get good leverage?
