So I purchased a 2004 f250 super duty 5.4l from a friend of mine to begin with it was the fuel pump went out so I put a new fuel pump in it fixed the issue now it's got a humming coming from the air intake I've been told before maybe charcoal box and just unsure of where to even start with this issue when you give it gas the humming stops.

 

Hums like a champ,lol.

Might be a good idea to check the PCV valve. Sometimes air rushing in at a special rate can cause loose parts to vibrate.

 

It has a new PCV valve on it.if you grab the air intake tube that's going in by the throttle body and squeeze it gently restricting it the humming stops

 

What if you took one end of the tubing off and looked inside ?
