Strange engine problem; Please help! S70 1999

Does it run as tho it has an NA engine? Reason I ask - I had a '96 Saab 9000 turbo that exibited the same kind of symptom. No power, no "kick", no RPMs - just like an average "run of the mill" car. Turned out that the waste gate valve (pressure relief valve on the turbo chamber that prevents over-pressure and to maintain a controlled pressure boost amount within the design spec) on the turbo was stuck wide open so no turbo pressure could build. I was suddenly driving a very well appointed $35k rocket reduced to running like a well tuned Yugo! OK - I admit the handling, seat comfort and stereo were better - but SHEESH! LOL! Was fixed by dealer under warantee (thankfully).

Not saying this is your problem - but saw your post and thought I'd bring it up. Hope this helps - or at least gives you an idea to investigate.
