Blowing Air?? Stuck Valve??

I just started to get this strange blowing air sound when holding steady RPM when I give it a little fuel it all of a sudden shuts off then comes back seems to stop after running awhile.
Any thoughts appreciated

I should add 99 F350-sorry---But I'm thinking valve too its a real snappy shut-off then as the Rpm drops it opens again.
Where do I find this beast and is it a repair something that can be attempted by a novice ?

there are 2 pipes one on each side of the engine going towards radiator i believe most call these intercooler pipes but any way check the hoses at both ends of each pipe( 4 hoses total) and check the clamps or see if they have popped off!

Definately sounds like EBPV. If it only does it when its cold and shuts off as soon as you hit the throttle then its workig properly. But if it feels like its coming on under load and holding you back then you can uplug it.

No horsepower loss --- just this loud annoying hissing sound.
Any idea if this is an easy fix?

Today I think I found the exhaust back pressure valve
has a small pipe vent coming from the assembly
Probably got a bunch of crap splashed up in there.
