Noises problem


When accelerating car starts to whistle. Seems to have gotten louder since a month ago. Talk to mechanics and all said something different. I changed the belt. The tensioner, erg pipe and had the alternator tested, still made noise. So went to the dealer to have it tested they said a pipe but it's still making the same noise, this is very annoying and not sure but this problems seems to be effecting the car speed performance and gas mileage. Any suggestions Went on different web site and many seems to be having the same whistling noise but no real answer to what it might be. Can't keep affording these guessing games.

Sounds like a vacume leak. With the car running lift the hood and see if you can hear it and try to find the area its coming from. Check the hoses in that area make sure they are on tight and not cracked or split anywhere.(Shut the car off before pulling any hoses off) hope it helps

Can you post a video with your phone so we can hear it? Cars can make a tremendous amount of different noises, it would be helpful to hear it at least
