I think you're supposed to see a cold idle of around 1,000 to 1,100 RPMs or so until the car warms up a bit (determined from the coolant temp sensor). However, there is little info available on the subject of cold-idle speeds for 200/700 Volvos. The service manuals and Haynes books show how to set the base idle speed with the engine warm, but nobody really discusses the cold-idle behaviors. There may also be a difference in cold-idle behavior depending on the computer. Switching from a 511 or 544 to a 554 should change the cold-idle-mixture, and thus might change the cold-idle-speed as well.
Sorry, I don't have any more info on the subject right now. (but I'm curious myself)
