Do you have an aftermarket intake on it? Some throttle bodies just have a tendency to whistle.

You have a vacuum air leak somewhere. Have someone get behind the wheel to run it while you track down the sound under the hood.

Has it always had the sound or have you done some work under the hood recently and now it does it?

Not necessarily. It could just be the throttle body.

It's always done that since I bought the thing.. It sounds like ... a lil whine or hum that raises and lowers with rpms. I like it...just wanna know what it is.

Well, wouldn't that mean that there's a bad seal under the throttle body or are some throttle bodies just molded wierd to make the sound? Having grown up before computerized cars and having had vehicles with 50 miles of vacuum tubing under the hood, I've always thought of a whistle under the hood as a bad thing.

Mine has always whistled also, I think it's just the stock airbox. When I switched to the JLT it whistled a bit louder, so I'm guessing that's the source.

id say its just your box or mayb a seal around the throttlebody...if you have any mechanix experience with basic tools itll be easy..just disconnect your intake hose and take out the 4 bolts around your TB...i believe theres a rubber seal around the inside...take it out and check it for cracks...if its cracked then theres your problem..if not put it all back together and check your airbox...one of the clapms may be off or something else small like that...if not its just the natural whistle your intake gives

Does it have a throttle body spacer in it? A lot of TBS's will cause that whistle. I have and Airaid TBS on mine and it whistles under acceleration then mellows out at cruising speed.

Some of them just whistle due to their design. Some even go as far as to drill a hole in the plate to reduce the whistle (I have no idea how that is supposed to work). :shigrin

It could be the silicone rubber gasket between the TB and plenum. Mine actually broke in half and I had to replace it.

So some cars are just happier than others. I guess you don't have to worry unless it also starts humming "Whistle while you work" or "Hi ho, hi ho" :hihi:
