I took the OLD cassette apart and the Cyl. 4 coil was gone. With the new cassette in, the DTCs report misfire on Cyl 4. So I figure somthing (Trionic?) caused cyl. 4 to misfire and that is what caused the cassette to go in the first place. I have a local independant Saab mechanic who comes highly recomended. I guess I'll have it towed to his place. :-( Thanks, John Hooven
