Nope, unless I got my head up my a$$ and just not seein it (not likely). I was pretty shocked not to find one. So much for an easy fix to my rich problem.

Check the wiring harness at the front of the engine by the fuel rail my o2 sensor harness beaks out of the engine harness and runs down to just above the axle and is clipped on a oil pan bolt is screwed into the exhaust pipe just under the header pipe. Mine is a 94 not sure if it helps ....

They are kinda tough to find. You may have 4 of them so keep looking farther down your pipes.
