i could not get my o2 sesor out of the stock o2 housing....i have the car running without the sensor in right now...so as everyone knows...its idle is very poor right now...probably missing correct? well...im curious how much that harness is...if its wroth trying to get the old one out or maybe just purchasing a new one...?

 

spray it down with liquid wrench and wait over night.. and try again..The o2 sensor aint cheap

 

yea...i sprayed it with pb blaster... let it sit for awhile...im have it soaking now... hopefully in the morning i can get it out.

 

I put my o2 housing on a bench, put a wrench on the sensor pushing down therefore pushing the opposite side of the housing up and hit the flange with a hammer. It took a couple hits. I did let it soak in PB for a while though.

 

Does a robot install those damn O2 sensors at the factory??

 

I sprayed mine with wd40 and let it site over night. Then I had to put a 3/8 air compressor rachet with a lot of muscle and it finally came out. That must of been torqued to 200+ foot pounds.

 

I don't remember mine being that hard to take off my first RS. Still have yet to try this current one.

 

well it will be hard im telling you....
i am getting a socket tommorow after work and we will see how that goes... does anyone know how much that o2 sensor harness is....

 

bro a socket will not go on there. The o2 sensor is like 300 bucks or more. let it sit overnight with some wd40 keep trying and spraying as you go. It will work this is not impossible they do come off.

 

air tools ftw with proper socket

 

If you don't know about it already, get an actual O2 sensor socket. It's a large socket with a small area cut out of the side for the wiring harness to slide into. Also, when you're removing the sensor, pay attention to the amount of force needed to remove it as you go. If it starts to feel like it's binding or becoming harder to turn, go the opposite direction and screw it back in a couple of turns. Sometimes the rust can build up in the threads and doing this well help avoid stripping the threads. Good Luck

 

yea that what i was talking about it terms of a socket one that is specially made so it can slide over the wire.

 

I bought that sensor for $150 online. I have a used one Ill sell to you at $55 shipped. ; )

 

Has more to so with the heat caking the sucker in there with no anti-seize put on at the factory

 

That front 02 sensor is kind of important so I'd either oil the old one and let it sit for a while or buy a new one altogether.
