@38 deg (ice-water)  => 648k
@60 deg (ambient) => 395k
@120-F (hot tap water) => 128k
@198-F (water boiling at 7500') => 35K

You are correct. The thermistor is reacting to changes in temperature.

The MS calibration parms call for three temp-resistance data points
but also a value for a bias resistor. I don't have one of those so I
entered zero ohms for that.

I don't remember if I used metal or the fibrous gaskets. That would
certainly explain the high idle. And also that the ECU was adding a
ton of fuel to correct the AFR. I'll absolutely check this.

My question is .. why would a type-3 FI engine require different gaskets?
