When 12 volts is applied, the coil wrapped around the metal strip heats the metal strip, which bends and closes the (or allows to close) the door. When the strip cools, it opens the door.

I could have the open/close backwards, but the point is that 12 volts moves the door by heating and bending the metal strip. That's all that thing does. There are no intermediate positions (i.e. it doesn't "adjust" idle continuously). It can, however be partially open, depending on how hot the motor is when you go to start it. As I recall, it doesn't take a lot of heat to move the door.

There is no sensor in there.

CIS (Continuous Injection System or K-Jetronic) is a purely mechanical fuel injection system. Anything electrical connected to it is purely for either fuel pump safety or to affect a change in the mechanical system. There is no brain, there are no sensors that send any sort of electronic information anywhere. CIS with Lambda uses an oxygen sensor and analog computer to adjust the mechanical fuel pressure in the otherwise unchanged CIS system.

The ONLY proper way to adjust the mixture on the fuel distributor is by using a CO meter in the tailpipe.

Getting the idle "just right" is somewhat of a ballet of adjustments, as all of the possible adjustments affect the idle speed to some degree.

Don't be concerned about how other 99s adjustment screws look. If all of the motors were perfect, and exactly the same, there would be no need for the adjustments (or you'd have a real electronic FI system like LH...). The important thing is the end result. Saab gave you all that adjustment room because they thought you might need it some day.

The throttle cable adjustment is ONLY to take up the slack in the cable. It is NOT for idle speed adjustment. The throttle should be resting on the stop. The screw in the top of the throttle body is what you use to adjust the idle speed. This adjusts the bypass air that goes around the closed throttle body.
