Well lets get some more people to chime in first. I'm just assuming but you never know, may be something simple. No, its not really hard to replace them, its just the o2 sensors for our cars is really expensive.

Wow. It has to be a damaged sensor. I just had the resonated version installed last week and no light. But I did have the privelage of having the boss Tony do it.

You can't eliminate the ones on the exhaust manifolds can you? The code come up as bank 1 sensor 1... isn't that on the manifolds, not the cats?

Yeah its your sensor same codes happened to me when I installed my headers. You can double check the sensor with an ohmmeter though. I pounded on it too hard trying to get it out of the cat.

I dont see how it couldve been damaged on install. That error code relates to the sensor on the manifolds not the cats. That is a precat o2 code. Those were not touched at all during install of the hfc's. Did you make sure atleast that sensors are plugged in and are not loose in anyway?

I lifted up the front end of the car, to put the steel wool in the J-bung, and I checked the 02 sensors, I didnt see any issues with them. I didnt look at the o2 sensors on the exhaust manifold, because Im not sure where to look for that. But its looking like thats where the issue is. It just makes sense.

You use an impact on the demon bolt? Anything at all other than a ratchet/wrench?

Did you beat on the ratchet/wrench with a hammer?
