Alright so today i cleaned out my IAC with some carb cleaner and I changed my oil. Im driving down the road a little later and I hear this weird noise. When the car is just idling it sounds like the cold air is sucking in mad air. But its so lound and annoying that I cant even tell if its comming from the cold air. Its almost like a whining noise. Anyone have any clue what it is. By the way when I cleaned the IAC nothing really came out of it. Like it was clean. I also have 34,000 miles. Thanks

Sounds like a Vacuum leak. Is the idle a little rough? Go back and check all your lines.

Thats what i though too but my idle is fine. Its normal. But i didnt really check the lines so thats probably the best idea. Thanks buddy.

Well I checked all my lines and its still making the noise. I guess time to take it to the mustang mechanic
