I am in the process of changing my oxygen sensor(s) on my '93 K2500 454 4l80E 4x4 Suburban.
I found one sensor in the exhaust pipe next to the transmission, pulled it, but the replacement provided Bosch 12014 will not thread in (while the removed sensor still will).
I also notice that the Chiltons manual, and Autozone's site imply that the sensor should be in the exhaust manifold, but I don't see one there.
Am I missing something obvious, or was I simply provided the wrong part, and my Suburban only has one in the exhaust pipe after the point where the Y pipe joins together?
Thanks!
