2000 Toyota Camry O2 stuck in manifold?

2000 Toyota Camry 3.0L V6, the bank one sensor one heater circuit is bad and needs to be replaced. The O2 code is actually causing the TRAC OFF light to come on. Tried to replace the O2 but whoever changed the last one must have crossthreaded it because i could not get a full turn out of it even after using penetrating oil and heating it with a propane torch.

Going to try again tomorrow to get the sensor out this time probably heating with an Oxy/Acetylene Torch. I'm worried about the threads on the exhaust manifold, i do not want to but a 250 dollar manifold. Any Ideas or Suggestions?

Use the heat BUT heat the manifold again before installing the new one.

Sell the Toyota as soon as possible.

I work on these all the time. Its not cross threaded. Its seized up. If you get it out I can almost gurantee you that the threads will come with it. Your choices are get a now or used manifold or have a muffler shop weld in a new bung for the 02

well if it was cross threaded then you would have had a code along time ago,plus it being a 2000 i will have to say its the original sensor in there,you just need to work it out,get it to move,sray wd40 then work it on and off eventully it will come off,if you heat it it should be easier ,a o2 sensor has to sit perfectly straight(or whatever angle its been set at)or the engine light will come on,so i doubt its criss threaded,
