Is your intake stock? Aftermarket CAI's will do that. Is the car running normal? If so and you do have a CAI, thats all it is

any one, sorry I dint mention that the car is idle fine and run great, just that whisling sound !

A vacuum leak will usually give you an eratic idle and low speed surging. If the car runs fine I would not worry about it.

is the sound there at idle?

Fords and their whistling intakes..

 

[Killa]

I heard the sound at idle, and I heard the sound change when the TB open.

I just dealt with this - it's likely your IAC gasket. Does the whistle wind down when you shut the car off? Does it more or less go away as you step on the gas?
Here's my story - I tried installing one of those IAC restrictor plates, but it didn't work. When I was removing the IAC, the OEM gasket ripped. I made a gasket from paper gasket material and used BOTH the OEM gasket and the one I made - and it whistled like a mutha.

every thing you say is right , but when I spay carb cleaner at the IAC the noise do not go away. but put my ear on the IAC and the sound is not coming out from their, I heard loud on on the passenger side top of the plug, where the air conditioning thing is.

OK, is it there at WOT?

 

[Killa]

im at work right now, I will WOT when I get off. I let yall know.

did few 5k shift and do not heard the whisling sound.

 

[Jbauer]

then i think you should start looking for vaccum leaks or maybe very tiny cracks on the intake manifold.

do u have the iac restrictor plate?

 

[Killa]

do u have the iac restrictor plate?

I do not have IAC retrictor place.

btw some time I saw my idle drop down to 500 from 800. like the car almost bog down. some time.

 

[Jbauer]

If it goes away at WOT i think it's a vaccum leak of some sort.. but i'd clean the IAC anyway..why not

 

[Killa]

just back from the garage, I did take out IAC and the whole TB and put some black rtv on the gasket, clean IAC, check all the hose, put everything back together, car ran and idle perfect, but that god dam whisling sound still their, **** IT !!!!

 

[Jbauer]

Theres a good chance you'll never find it LOl.. i had the same problem.. it got even worse on hills with slight load on the engine. I just got a exhaust loud enough to drown it out.

I'm still betting it's a vaccum leak though.

do they selling dye color to check leak for vaccum leak, like how they did it to coolant leak. like after you put some color in the vaccum hose, then wear a special glass so you can see the color and know where it leak from. that would be cool !

 

[Jbauer]

No, but they do sell a machine that injects smoke through the vaccum lines..if you have a leaking line or open line, you'll see smoke come out of it..you'll probably have to take it to a shop.
all depends on how much this is bothering you
