After a 5 minute drive to the GO station this morning I noticed that my idle speed started going up and down between 900 and 1200 rpm.

Anybody know what the problem is?

maybe also some air in the cooling system...

Yes.The second one did.

My coolant level was low. I decided to drain the cooling system
completely and put in fresh coolant (50/50 ratio).

if it goes up down when u stop ,comsume more gas rpm increase when driving . it might be your O2 Sensor or MAF .
