Hello, Can anyone help me with diagrams or pictures on how best to find the location and replace the oxygen sensors.
I understand that there are several. I think mine is faulty on the upstream(before the cat converter)
thanks.

Starting at the header flanges, follow each exhaust pipe toward the rear of the truck. You'll find an O2 sensor in front of the cat and behind the cat on each side...4 in total.
