I've owned a couple of these 3800s, and my last two both made a rather loud howling noise through the intake. It's almost like a pulley noise... except it sounds like it's coming directly from the throttle body. Is this a normal thing? I cannot for the life of me think of what might cause it. Last car was an Olds 88, current car is a '99 GTP.

Let me guess, it's only when it's cold started or you have a intake.
That noise is the air rushing past the IAC passage inside the throttle body.

Yep on both counts.
Thanks for the response; been bugging me for a few years now.

It's like a shovel on concrete or a angry vacuum cleaner type sound.

Yes, exactly! Not at all a pleasant sound really.

My black car on cold starts sounded like the end of the hose on a Hoover lol silver car isn't as loud.

I knew that. I just didn't know that's what caused that sound. That's disappointing
