What you describe, sad to say, is normal. As you may be aware, the actual throttle plate is not physically connected to the accelerator pedal, as in the good old days. It is a "drive by wire" system, which means your foot pedal operates only a variable resistor (potentiometer) which then tells the control unit how much throttle you want. The ECU then operates the throttle plate for you via an electric servo motor. SAAB engineers, at some point in time, decided that the throttle should be released slowly to reduce the emissions that occur in a trailing throttle condition. This was a very unfortunate decision, IMO, as it makes the driver feel disconnected from the engine and drive train during shifting, and seriously hampers the total driving experience. The reason I am so aware of this is I purchased a 2000 9-3SEC last year. This was to be my summer fun sporty car. I searched around and could not find anyone who reported being able to change this characteristic (ECU reprogram?) so I ended up selling off the car because of it, along with the tendency the convertibles have for cowl shake. I could have lived with the cowl shake, or worked to reinforce the chassis, but the throttle thing just pissed me off too much. In the case of an auto transmission, it would be a moot point, but part of my definition of "driving" is clutching and shifting. Otherwise that car was a beauty. Gotta love that HOT!! It was hard *not* to spin the tires on acceleration. ;-) -Fred W
