I was replacing the upstream air fuel sensor on my 2002 Tacoma 3.4 V6 2wd in response to a P1135 error code.
I foolishly applied torque to the nut that was apparently cross threaded (it was very stubborn coming off as well.....I knew there was some problem) and sheared the stud that comes out of the exhaust for the sensor to mount to.
Anyone have any ideas for me? Is this stud replaceable? Or this section of the exhaust?
Any help or advice would be much appreciated!
