I recently purchased a '98 prelude (base) and need to do a couple of things with it.

Has anyone here done an O2 sensor install and has there been a write-up? How difficult is this and about how long does it take?

I also need to upgrade the pads/rotors and want to change the brake fluid while i'm at it. Is it too ambitious to think that I can do the O2 sensor, brake fluid, pads and rotors, and possibly an oil change in one day?

 

ah no if you know your stuff you can do it in one day. i did my exhaust/headers, valve cover gasket, plugs/wires, intake, throttle body spacer and the pads rotors and braded brake line just over half a day.
that is i also had my girlfriend help me.

 

oh but if your doing the o2 sensor i figure it's not that hard. just remember not to touch the end of the sensor thats what the muffler shop told me it could mess up the sensor for some reason

 

the sensor was pretty easy, unplug the wires and take off the little clips that hold the wires in place then unscrew the sensor. then intsall the new one and put the wires back in the clips then plug in the sensor. thats all i had to do on my 5th gen.
