I have a whistling noise when accelerating...
I have an '00 with 48,000 miles.
Whenever I try to accelerate through a gear, when the gas pedel is pushed in from 20%-40% I get this high pitched whistling noise. It starts off very high pitched when the pedal is pushed in around 20% and then around 30% it gets lower until it fades out around 40% pushed in. I only seem to notice this in 3rd-6th gear and happens when I'm coasting and then start accellerating. It happens all the time and isn't bad by any means, it's just strange. I don't get weird looks and have never had anyone even mention it to me but I'm just curious.
Any ideas?

This has been discussed in the forum many times, just do a search on "whistle" to find some. Below are two examples for you.

Thanks, I guess I just didn't enter the right key words in the search, as I did before I posted, as I do before making any new thread.
Those still didn't explain why it's happening. I have stock airbox with K&N filter, but it did this before I changed the air filter element. The car has never been modded before, as it was driven by a conservative retired man.

Anytime air flows through a pipe, there is a distinct possibility that it will make a noise. This is the principle behind musical wind instruments. It just so happens that the design of the stock intake (airbox, piping, throttle body, etc.) induces this sound. Some aftermarket intakes are even louder as they amplify the sound. It's just physics.

The difference between air intake whistle and electronics "hum" is very distinctive for those who know what they're listening for. They are not the same in nature or in origin. Most obvious is that intake noise comes from the engine bay. Electronic hum eminates from your speakers and electrical components.
He didn't state if he modified his car.
AEM intakes are the worst culprit of intake whistle, from my experience.
My car whistles and it's stock under the hood, it's only heard under light acceleration like justin claims.
I've had electrical interference before on vehicles and the sound eminating from my car sounds nothing like I've had before. It does not come from a speaker, or the head unit.
And by the way, how is someone supposed to hear the whistle from the engine bay when accelerating ? you can only "assume" that's where it's coming from since you can't put your ear next to the intake and drive at the same time.
You're a moderator, you shouldn't have to put people down when explaining things, especially to me, I've owned my car for 2 months and am learning and trying to be active on this board.

Dre I felt the same way about xviper's comments to people too so I know what you're saying. I felt he seemed a bit harsh at times, then I thought about my experiences on another forum. I'm a moderator at a cichlid forum (cichlids are a type of aquarium fish) and keep several fish tanks and have invested thousands of dollars in them and my African cichlids. I found that people started asking these questions over and over and over again on the forum and it got tiring. I noticed myself giving them very short, non-friendly answers because I was so busy answering them all. I wasn't trying to be rude, it's just the way I was coming off and I then tried to be a bit more friendly after that because after all... newbies are newbies no matter what forum type it is
I don't think he's trying to put anyone down really, just that he's coming off that way because this is such a busy board and he's very direct in his answers.
