Great suggestion I will investigate thoroghly. I have had the exhaust crack
a couple times now before the O2 sensor. I had it welded each time so I
thought it was OK.
If it is that sensitive, then I will check it out. Thanks.
I have been trying to troubleshoot the two codes Idle air control and temp.
I Idle air is supposed to cause the engine to lower RPM's when connector
disconnected but mine increases rpm's. Go figure.
Thanks everyone for the help.

The emissions people here told me that a leak in the exhaust system will
throw the computer off by giving the O2 sensor false readings, therefore
your O2 sensor may be functioning properly but it could be getting
exhaust contaminated with fresh air thereby sending inaccurate data to
the computer. Of course, Emissions wouldn't count the cost of replacing
the header pipe on the old WBX toward the $200 minimum for a "work
toward compliance" waiver (it was way more than $200), but they would
count the cost for a new O2 sensor, which I didn't need. Anybody need a
slightly used WBX header?
