Definitely the intake. Next time it does it, carefully move the throttle in or out a little and you can make it constant. It happens the most at low speed, such as in a parking lot. It almost sounds like brake squeal.

 

yup your right intake i tried the volume thing didnt work but it got higher the more gas i gave then it would cut out. So is this just a loose hose or something i can fix or is something imma have to live with

 

Not sure what kind of intake you have, but the stock won't do it, most anything else will (i imagine the j's may not, and the arc may not)

 

got the kn fipk

 

I heard the same noise in my friends car. I know its your radio %100. re wire amp

 

Does it do it with the radio off? If it's the intake you're stuck with it. the stock box masks the noise.

 

heh if its a whistling sound only when you give it gas at that certain rpm range then its your intake, when i first got my car i wondered about it too but i loved it so i took the cover off the intake box and now it whistles louder i can make it whistle as long as i want it anytime now, its fun cause people that doesnt know what it is goes

 

im pretty sure its my intake now but ill try turning off my amp and we'll see what happens

 

I have fipk and have exactly same noise when i press the gas. Doesn't pitch of the sound increase as you accelerate only in certain speed range?

 

I have the K&N also and it produces the same annoying whistle. Mine appears at 3200-3400 rpm and it is always as I am accelerating. I have not yet found a means to fix it other than turning the audio system up.
