Hey all. I got the parts in and tried to change the o2 censor. There is something blocking the censor that wont allow me to unscrew it. I have attached a pic. Any ideas? Thanks again. Image Unavailable, Please Login
Could you get a wrench on it at all? You could try the wrench that John showed earlier in the thread. If you can get a wrench on it and you can't turn it, there is a good chance it is "welded" on and may require you removing the cat to get it out and possibly chasing the threads in the cat to allow a new one to be installed. Hope that isn't the case but it happens.
Frank, you might want to use some PB Blaster and spray the CAT nuts and the O2 sensor. Let it penetrate for a bit - makes breaking stuff free much easier
If you get that wrench that John showed you may not have touch the exhaust clamps. It is designed for situations where you can't get a regular wrench on it. I would think harbor freight would have it. I got mine and an indi auto parts store. I would try that first.
Were you able to get it off and replace the sensor? If so, has the issue resolved itself? I think mine is starting to show signs....
