Sounds like you have a vacuum problem somewhere in the intake. Could be a vac line or a crack in the boot on the throttle body. The system is getting varied readings of how much air is coming to the engine and it's trying to compensate. Used to be a frequent problems with my 16V VW's, and was attributable to the ISV valve. Not sure how Saab does theirs though.
