Anyone know how to replace 02 sensors in a 92 NSX?

I would agree that if things were hot they would come out easier, but the "fun" that goes along with that I can do without. JMO.
HTH,

I didn't, nor was the ECU throwing any codes. The giveaway was the car was running fine when cold but when warm had a rough idle and a part-throttle stumble around 3K RPM. At WOT/warm it ran fine, and it was easy to detect the transition from closed-loop (O2 sensors engaged) to open-loop (O2 sensors ignored) mode when going WOT. I don't know why the ECU didn't detect the bad O2s. I guess sometimes we have to use our good ol' brains instead of listening to a computer. :smile:nis350 said:Just curious. Did you all get the engine warning light with the bad 02 sensors?
Larry Bastanza said:Hi Gary,
Nope, not me. I have never used any penetrating fluid of any kind. I was taught never to use it. Did you have the tool that is like a 5 sided deepset socket?
Mine has never failed me, and I have had some pretty stubborn 02 sensors from cars up here is the NE.

NSXTech said:From experience, I would not change them if they work well, but if you have to, most parts stores sell a crowsfoot type O2 (22mm or 7/8") tool that makes it fairly easy but soak them first in a good rust penetrant. Put a tiny amount of anti-sieze on the threads, being carefull not to get any on the sensor. It will be useless if anything contaminates the tip.

Larry Bastanza said:The connectors are not. You will need to splice then into the original harness wiring. That is why Russ explained above you need to match up the wire colors as he described. Really pretty easy.
BTW: Did you have the wrench shown above, or something else?? Just curious.
