Default Cold Idle problem

Last week my '91 olds started idling very rough, up and down fluctuations while cold. After about 2 min. it smooths out and does just fine? Temp Sensor? Other ideas?

I had issues with my TPS and IAC on my LG3 olds. similar symtoms, problem seemed to be with the IAC motor sticking though, however TPS voltage was all sorts of screwed up

IAC motor was cleaned over the summer, maybe I need to do it again. Voltage on the TPS is within specs.

Thanks
