Start with checking the blades so that they arent stuck then check TPS and IAC to make sure its set correct. Check out https://www.thirdgen.org/newdesign/tech/tpimod2.shtml. Maybe your IAC are fried..

Good luck..

Livin' the Stereotype

 

My '85 Firebird does the same thing EVERY winter ever since I drove it, brand new, off the dealer's lot. The ECM apparently never caught on to slow the idle down once the coolant reaches 180*. Only when spring comes around and the outside temp stays above 50, then the idle comes back down and it nice and slow. I've checked the resistance of the coolant temp sensor (not the overtemp switch) and it seems to be O.K.--as the temp goes up, the resistance drops.

My other car, my trusty parts-gofer/dirt road beater, 1985 Olds 88 does the same thing when it gets cold (the car runs much better than it looks!) So it must be a common problem with the ECMs of that year.
