Thanks Steve,I have a scantool and the coolant sensor seems ok. Here are
the readings.
Temp sensor 200
TPS voltage .58
MAP 1.2v
about 80 O2 crosscounts in 5min running
inj pulse width 100ms (this can't be right, may be a bug in scantool)
idle speed 950
and for some reason the scantool does not report the BLM or Itegrator.

Thanks again for your time.
