I hate asking about something so cheesy and couldn't really find anything in a search.

anybody have any tips on the bes/easiest way to remove the O2 sensor?

i like to believe that i am mechanically inclined and i have done tons on my rx7 but never an O2 sensor.

BTW, its a 89 NA

Thanks

Go to a parts store and get a Bosch O2 sensor. Remove the one in the car now with an open ended wrench (I dont remeber the size). Cut the connector off of the old O2 sensor...BUT BE SURE TO leave enough wire for you to be able to splice the connector onto the new Bosch O2 sensor. Install, and connect.
Ur done!

already knew about splicing in a generic one, i was jst hoping there was an easy way to get down in there. doesn't seem like there's really any room.

think its easier from top or bottom?

I would suggest spraying it with lots of penetrating oil before hand. Maybe let the oil soak in for a few hours and spray some on every now and then. Those suckers are usually frozen in there prestty good. they make special sockets to remove the sensor without cutting the wire, but if you're replacing it then just cut the wire.

Easier from the top with the stock manifold. Once you got the header you must go under.

Best to use an O2 socket. It's a deep socket with a slit in the side for the wire. I attached a universal to a long extension. A lot of umph and it will break loose. I found it easier to break loose when car warm. Line everything up when cool, the just slide it on when warm. I broke it loose then removed after cool down.

Sorry, post for a TII, you have a N/A.

I just replaced mine, bought the 02 socket and still could not get it loose without soaking it in WD-40 for about a half hour. Bought the Bosch and needed to splice it, connector did not match nor was it long enough even thought the original looking NGK was on.

Make sure you use the heat shrink stuff that can handle the engine tempurature on the spice.
