Ahh, someone finally asked! I though I was the only one that heard that
for awhile there! It's normal, but VERY annoying I agree. That's one of
the first things I asked my service manager about. It's some emmissions
device if I remember correctly (I'll find out for sure later when my
dealers service dept. opens). Pop your hood and look on the firewall just
to the right and above the TB. There's a little plastic can looking
thingy hanging there with a inlet hose and an outlet. It's attatched to
the firewall with a bunch of rubber bushings. That's your culprit and
there's nothing you can do about it. (At least that I know of) My
service manager said that if all those rubber bushings weren't there you'd
hear it even louder! Oh well.
