[1998 Brickyard]

It seems to only happen when the car has been sitting for a while (or has sat overnight). I don't think it is a belt that is making the noise.

Each time I start the car in the morning, it seems to to take 20 - 30 seconds to "settle down".

This goes on until the engine idles down a bit.

Mine does it too, I have a 1LT Auto.
My other Camaro, a 1998 SS, makes the exact same high pitched whistling noise every time (hot or cold) for 20 - 25 seconds; I always thought it was something charging up such as the A/C, a capacitor for the air bags, ABS ???????
