They are welded in to the exhaust stream so as to prevent easy removal, its a government thing for the protection of our air quality.
I'm not a mechanic, but I'm pretty sure you have one O2 sensor just before the catalytic converter and one after. The first checks the function of, and regulates, your fuel control unit, and the second checks the efficiency of your catalytic converter. My #1 O2 sensor is screwed into the exhaust pipe about a foot or two before the converter and kind of looks like a spark plug. On a 2003 Isuzu the O2 sensor is on the driver side of the engine compartment about a foot down from where the exhaust pipe comes out of the header. Just follow the exhaust pipe out of the engine and you will see it. It looks like a spark plug sticking out. It's pretty easy to disconnect the wires, unscrew it and replace it. You will need a 7/8" open end wrench to unscrew it. Good luck. * 1999 Oldsmobile Aurora's actually have 4 O2 sensors, 1 on each header and 1 before, and 1 after the catalytic converter...
It has four (4). Two located before the catalytic converter and two after it. Edit: This depends if you have an OBD-I model or OBD_II model. Since all cars after mid '96 are OBD-II then if you have a V4, yes it has four (4). But if you have a V6 engine it only has three (3): a preconverter sensor in each exhaust manifold and a post-converter sensor.
I own A 1995 Isuzu Trooper 8 cyl. I have been having the same problem and with much research and what-not i have found out the Oxygen sensor needs to be replaced, as well, because i have waited so long to replace it, the Catalytic converter now needs to be replaced. I hope that your car has not gotten to this point because the cost to replace the catalytic converter is $700+. the cost to replace the O2 sensor is $270+. The cost to replace the sensor yourself is 40 dollars and the cost of the converter itself is 80 dollars. I know the sensor is fairly easy to replace but i have no idea about the converter. I hope that helps.
I had this problem a few times. First fix was a piece of ply wood on the engine side of the wall with the cable through a hole in the ply. Second was 1/4" thick aluminum about 2" wide with about a 1" hole for the collar piece on the firewall, (engine side) It lasted maybe 8 years, but the fire wall cracked in too many places and finally failed completely. Last year I got two pieces of 1/16" steel and shaped them to sandwich the firewall. The driver side piece had an angle welded to the right side. This welded to the rib on the right side of the clutch cable hole after the plates were bolted with the existing bolts. The engine side had a strip welded on the top edge (to form an angle) that was welded to the "gutter" rib that runs across the upper part of the firewall. Once completed, I could shift again without grinding those expensive gears. It's worked like new ever since.
