yes, errr no. Since that post, I did change out everything I could, including the TPS. My father had a 1997 CS so it was a real help to swap parts. When I looked at the o2 output, there was a slight stagger on the voltage swing but nothing I could pin point. I just finished a full 3" exhaust upgrade and ECU. I was swapping between the stock and upgraded computer for a few days and it all but goes away witht he new computer. My stumble was significant when the weather was very humid/wet so it's hard to say if it's completely gone. But I will post the next time the conditions are right. I've guessed that some fuel mapping in the HOT ecu's from saab(Aero) was just on the boarderline. Some aftermarket tuners even claim to clear this up with a new computer and it looks to have worked. I had another in depth post where I was measuring the resistance in all the temp sensors to make sure they were all within a few ohms of each other. Check them, block, intake, head. Block is between cylinders 2&3 under the intake. Head is near the thermostat and intake is in the pipe from the intercooler to the throttle body. good luck.
