Intake making loud humming noise
OK this has been a issue since I bought the truck and it's only getting worse. Whenever the truck gets up to operating temperature the engine makes this loud humming like noise. Well today the noise drove me up a wall so I was determined to find it which I did. It's coming from the intake tube that goes from the air box to the intake. When the lid on the box is closed the humming is loud but somewhat quiet. But the second I opened the air box the noise got like 10x louder. I need to know how to fix this as I put 100 miles on my truck a day and I can no longer drown out the noise it makes.
Here's a poor sound clip taking from my phone, the sound isn't exact as my phone sucks. But you get the point it's loud.

Here's an article concerning the IAC valve. I too am having problems with my IAC valve causing a humming noise in the air intake. I cleaned it with carburetor cleaner and set to let dry. It actually made it worse for me. The humming stopped, but the truck stopped idling high enough to prevent stalling.
This article is from Ford and you can take their word for it, to just buy a new IAC, but they only see it as a short lived solution.
Note: This is for a Crown Vitoria, but the application is the same. Here's the link to the article.
