I wouldn't think that there would be any time concerns, as to the ECU, between starting and a few minutes later,..although I could be wrong. Wouldn't surprise me, for sure.

I did check the idle switch, it is in correct position so that when it is moved off idle, it slightly clicks.
With some other cars, when the engine is cold, the ECU runs open loop and slightly rich waiting for the O2 sensor to warm up, then it uses the O2 sensor signals to tweak the stoicheometric mixture. But, I do not know about the 87 Carrera firm ware.
