Hi Arlen,
    The o2 sensor is bad, very high probability. Possibility of a loose /
wet  connection on the temperature 2 sensor. To prove try running in open
loop( O2 wire pulled) or just replace the o2. Ron (bus depot) has generic
bosch 3 wire sensors at a good price if you can do a bit of soldering. Good
luck with your quest.
