Loud Humming Noise from my engine of my 2003 expedition
When I let off of the gas pedal, I hear a very loud sucking noise coming from my engine. It only does it when my expedition coasts, and gets louder at a high rate of speed. You notice it more when my truck is gearing down. What is causing it to do this and how do I fix it?
