weird whistling noise..

I have this weird whistleing noise ...sounsd like an intake leak..but theres nothing leakiong..i tried the carb-cleaner trick..i couldnt find a thing. anyone got any clues? sofar i checked the whole intake after the filter to the tb... i touched the tb before..to get to the IAC..anything around there that could cause it?

oh, and when my throttle is ~1/4+ open it goes away..

Could it be a bearing? Or maybe the lid etc. is not tight and the engine sucking in air is causing a whistling sound, but with more rpms I would think it would get louder. Check the pulleys and see if its coming from there.

I hate those noises that you can't pin point.

yeah.. so i was thinking, could it be the airfoil? with that little hole drilled in it? cuz at higher throttle, less air through that, right?

Can you only hear it when your driving or is the car parked?

Might wanna take the belt of fand check all th pulleys out.

its on whenever the car is running, and its lower than 1/4th throttle or so..

so belts/pulleys make sense..

wait i just thgought about it and it DOESNT make sense that its a pulley. cuz.. it doesnt depend on the engine speed at all..only the throttle position i can be going 1Krpm in 5th gear and when i punch it the noise goes away...

or i can be going 4Krpm in 3rd and when i punch it, it goes away.. when im sitting at idle its still there too..

Let it idle and check under the hood. Go to a parts store and get one of the car stethoscopes so you can hear around and pin point alil better. This is just plain weird.

well, quit yacking and start sluething. :disappoin

hahah i tried.. i took apart the front of the tb again.. im gonna go wrench away again this weekend.. but yeah.. school finals coming im getting ownedddd :(

i know its not the intake box and stuff tho.. its somewhere after the MAF, i disconnected everything from the front of the MAF (no airbox, aircleaner, etc) but.. it still made the noise. i checked everything after the MAF to the tb..and its also not the problem

can vaccum hoses make crazy loud noises lkike that too? its really loud, i can hear it over my car speeding on the freeway w. the windows down.
