Dennis, My 87 9000S does the same thing, when I start it for the first time during the day, or it has been sitting for a while. It is not your O2 sensor. It is the AIC valve (Automatic Idle Control Valve). My Saabtech friend has an 87 9000T. His was doing the same thing. Recently, he took an old AIC valve, cleaned it up and installed it. There was a major improvement, but he told me he will get a new one. Townsend imports has the AIC valve for $121.03. Impex Distributors, 1-800-736-3550, quoted me a price of $125.28. Good luck. Mine has 154,369 and running strong. Ken Washington 87 9000S
