Re: Intake whistle TSB (DanC5)
Does it only apply to '01's or to '02's as well? Which VIN #'s are affected.
I too think this may be what I am hearing on my '00 (thinking it was belt noise til I read this).

Re: Intake whistle TSB (C-5 TECH)
I've got that whistle on my 2001... it's funny somone asked if it was supercharged when driving in my car...hehehe!!! But I agree, I'm kinda leary about a dealership tearing into my vette over that whistle noise.
