I have asked before but no one replied back. Does anyone else get that whinning or howling noise from the engine when you excelerate? I notice it more at speeds around 60+ the noise happens the second you tap or press down on the foot pedal.

I had that problem on my '98 Expy...cant remember what I found but it was definatley something with the air flow, do you have any mods done?

It depends on what year '05+ might be a cam phaser, 98-04 could be a tentioner pulley, My 03 had terrible problems with some pulley.

It's an '04 model. No modifications done all factory correct. It now seems to be fading away or I am getting use to it. I was told that Fords just make that sound.
Very odd if you ask me.
