A little background..
My jeep has about 144,000 miles on it, I bought it used with almost all the stuff it has on it, already like that, so I don't know very much about all of it. It has been driving just fine, but it started making this weird whistle.
The problem..
It started making a whistling/ squealing sound, a real high pitched sound, and it only happens above about 20 mph when I press the gas pedal down to a certian point, it's not a metal on metal sound it's like an air-whistling sound. The pitch of the sound changes with how far I press on the pedal, and if I press the pedal down far enough, the sound stops, but then if I let back off the pedal a little, back to when the squealing started, it starts whistling/squealing again. But if I completely let off the pedal, it also stops. The pitch changing has no correlation to the rpm's, only with how far the gas pedal is pressed down. I know from looking under the hood I have a Afe cold air intake, and I have done a lot of searching to try to find an answer to this, I can't seem to find anything quite like mine, I have read that cai will make this noise, but why would it just now start doing it? So I went and tightened the hose clamps on the cai, and test drove it, with no change. It still whistled at certain points when pressing the gas pedal down ,above 20 mph. Because it doesn't make this sound while revving it in neutral, I can't find the exact spot where the sound is coming from in the engine compartment, but I do know it is coming from the engine compartment. What could this possibly be? Anyone had anything like this?
