Hello! I've discovered a strange noise. When my driver's side window is down, I can hear a very high pitched whistle or squealing just around 2000 rpm. It's easy to confuse with the sound of other car's brakes squeaking, but I confirmed that is not what I am hearing. Could this be related to my cold air intake? I installed an aftermarket intake and throttle body about a year ago.

Have to be a little more specific about the speed of the car when it's going it. Also what gear, grinding, ect. Could be anything from reading the post.. And that doesn't help

The noise is in the 1500-2000 rpm range when I am traveling at highway speeds, 50-60 mph, and only when I am pressing the gas pedal. 2nd or 3rd gear. I have a 2006 GT, automatic. 90k miles.

Is it the windshield? I had an f250 that had an high pitch noise coming from outside while traveling at certain highway speeds. Took it to the dealer and they found it coming from the windshield. i was missing some adhesive/weather stripping that when the wind would hit it at a certain speed would make a whistling noise.

If it comes and goes with being on the accelerator, then you've narrowed it down to drive train, intake and accessories.

A fuel injector not seated properly..Had an issue similar on an old 1980 Porsche 911SC..Once in place properly..Whistle stopped..Hope this helps...

I've never messed with fuel injectors. Is this simple to get it seated properly? I guess I still need to browse the boards to look into this procedure.

What possible repercussions would result if I let it go to long?

Thanks. If it is the intake, any ideas where? I tried tightening the hose clamp that holds the filter on, as well as the hose clamp that attaches to the throttle body. No change in whistle. Could there be a hole somewhere that could cause this?

You should notice hesistation in motor if its really bad..Just ensure the injectors are seated firmly in place. I checked a few other sites that claimed they can be knocked loose easly..And do whistle if there loose...Also check the vaccum lines, another whistle maker in the engine bay...Hopefully something easy as this is your culprit....
