Did you have any trouble getting your o2 sensors off?? Apperantly, mine were installed without any kind of lube so after 27k miles, they are absolutely stuck in place. We had two full grown men pulling on the wrench, trying two different times, and the third time we took it to a shop who also couldnt get them off. So yeah, did you have a problem cuz I am going to just break mine off and buy new ones.
