o2 sensor question

[bmxfelon420]

Would it be a good idea to replace my o2 sensor if i'm unsure of the age of it? Is it a "service interval" type replacement thing, or just when it breaks? Or is it cleanable or something? It came in the car, i was just wondering if it'd improve economy/performance to get a new one.

It's a wear item, so replacing it is never a bad idea. Be sure to get one from NGK/NTK or Denso. Do not get a Bosch sensor. They don't work properly in our cars (a handful of people have had success... but most don't work at all, or fail in 3 months.)

If your CEL isn't on, and the car isn't acting funny... then it may not be necessary. However, it's not a bad idea to do it as preventative maintenance.

I'll buy another one, since in certain weather/randomly it seems like it doesnt run as well as it could, but other times it runs great. I have a few other things to go over to make sure it's up to par, but otherwise it was one thing on my list i wanted to cover. Also judging from the state of the car when i got it (except for the excellent compression) everything was kinda shitty.

some how my fan cut a sensor wire and i think that it is the o2 sensor and the check engine light all ways stays on now. do u think it will be hard to replace?

[deevergote]

With the right tools, no. You could always just splice the wire back together as well...

Besides whats listed... I have a Bosch sensor, and I notice the check engine light goes off every once an a while. Usually if the weather is hot or cold i notice. Never stays on if I turn it off and restart it, but stays on the computer if I test the code jumper. Think this sounds like a Bosch issue, or something different?

Bosch are crap like said above , and speaking from experience.

OP , o2 sensors are not cleanable. They are highly sensitive sensors.
