Ambient temps are around 30f. Idle kept oscillating and died 3-4 times before warmed-up. It seems that once the car is in open loop it idles fine. MAP, new, ICM (Ford) new, Vacuum good...Looking for an ohms chart to see if impendance on the CTS is consistent at these temps.

'87 GT

With wiring connector disconnected...

50 degrees F = 58.75 K ohms
68 degrees F = 37.30 K ohms
86 degrees F = 27.27 K ohms
104 degrees F = 16.15 K ohms
122 degrees F = 10.97 K ohms
140 degrees F = 7.60 K ohms
158 degrees F = 5.37 K ohms
176 degrees F = 3.84 K ohms
194 degrees F = 2.80 K ohms
212 degrees F = 2.07 K ohms
230 degrees F = 1.55 K ohms
248 degrees F = 1.18 k ohms


I'd dump codes and see if the ECU sees something it doesn't like
