Check engine light is on in our 98 civic lx sedan. Every honda i have had it was always the O2 sensor. This one seems easy enough , right at the top of the manifold. Just wondering if anyone has had problems with these before? PB BLaster and a breaker bar? Or should i just take it to a trusted mechanic?

thanks in advance.

 

you can do it yourself but the sensor will be heated to the manifold and may be a bitch of a time to get out/off.

But it's a job anybody can do

 

I just remember hearing horror stories of snapping the 02 sensor leaving just the threads in the manifold.
