212 850

Hi
What do people know about this code.
My 93 850 gives me this code after 2 miles of
driving after reseting the computer.
Is the o2 sensor toast?
Can it be cleaned? Shock it in cold water after heating it with a torch?
is the air mass meter involved?
Should I just bite the bullet and replace the o2 sensor.
Maybe swap one from a junkyard?
any Ideas
Thanks
old timer
