If you have the 2.3 L I-4, then you probably have a bad Idle Air Controller (they are notorious for going bad). It will cost you about $100 from the dealership for the part alone. It is located on the back side of the intake manifold near the center of the vehicle. It is black and has an electrical connection on top. There are 2 bolts that require an 8mm wrench or socket to remove. There is a gasket between the idle air controller ond the intake manifold. (Make sure when putting the new one on you put it on the opposite direction as you took it off) . It will basically look upside down.You can change it yourself in about 5 minutes.

Where is throttle pedal position switch b on your 2000 Saturn sl 2?

The throttle position sensor is on the throttle body. That's the part of the engine that controls the amount of air allowed into the engine. To find the throttle body, follow the air intake routing toward the engine. The throttle body is the part that sits on the intake manifold. To find the throttle position sensor, follow the throttle cable to the throttle body. If it helps, have someone press down and release the throttle pedal while you're looking for the throttle body/position sensor. The throttle cable causes a shaft to turn, that's the part that controls the air coming into the engine. The throttle position sensor is connected to that shaft.
