460 EFI - Annoying Air Intake Noise
I have a 1995 E350 with a 460 EFI and there is a loud noise coming from the outside air intake hose after the air cleaner. It doesn't happen when you first start it up but once the engine is warm and it is under acceleration the noise will start. Even once you slow down or stop the noise will continue until you punch the gas pedal and it will stop. The noise sounds like a loud fan or a plane taking off. I have asked several people and no one can figure out what it is.
Has anyone experienced this or know what's causing it? Is it something I need to worry about?
Thanks[/align]

Dave,
Thanks for the information. The odd thing is the noise seemed to have just started. I took off the air cleaner and narrowed it down to the outside hose. I know I don't have a vacum leak aswhen I squeezed the hose the engine almost shut down.
Not certain if this is related to the same problem you had but again I appreciate the response.
