Interesting-
James Dean and just-ntime say idle increases when iac unplugged.
Me, Robpruijt, and johnflight1 have idle decreasing at 80c when unplugged.
I have measured current and voltage on mine in running engine and bench tested with 12v. All seems to be good.
Why are three of us (M103) getting the same results and opposed to the other two?

I think the immediate die on cold start is related more to the accumulator or check valves, but the car was just driven 500 miles away (with no problems except the start issue when cold = starts fine while using during the day with short (2 hour) stops) and won't be back till Tuesday.
