Well Chuck my euphoria was short lived.
KOEO eha reads 059.9. Depending on which way the leads are plugged, in it reads either pos. or neg. but still 059.9. (what is the correct connection, ecu to meter pos. meter neg to eha or the other way round, nobody seems to know)
I can unplug anything, C02, temp sender etc. nothing budges it off of 059.9.

The airflow sensor (the no longer available part) I could only find the measurements for adjusting it. 0/70 volts DC +/- .10 volts. mine read .76V. when I unplugged the airflow sensor the engine revved up a little and then when I plugged it back in the throttle sensor plate got sucked down a little and the engine returned to normal idle, so it appears to have an effect on the engine.

I'm out of ideas
