My 90 Saab 900T recently developed a strange idle pattern. It revs from 1000 to about 1200- 1300 and then drops back down again and repeats this continuously. Also, I noticed a strange hissing noise from behind the dashboard, AC compressor maybe? What could be causing this? Any help would be appreciated. Paula
