Question about 2001 Pontiac Grand Am SE
No, the idle is controlled bu the throttle position sensor, and I suspect that yours is having a problem. The idle is controlled by the ECU, and is not adjustable manually,.

The idle speed is not adjustable, it is computer (PCM) controlled, you can turn the screw for the hard stop, but the computer will just over ride that adjustment for the most part, what I think you may need to do is clean the throttle valve and the idle speed control air bypass valve, use carb spray, spray it in the intake with the engine running use the at least 1/2 the can, the engine will try to stall, keep it running, after you are done disconnect the battery for 10 minutes, reconnect and drive a few days so the computer (PCM) can relearn your driving habits and set the idle correctly based on your driving.
