Hi, new to the site & new to my 99.5 F250 7.3L. Spent more time than I care to admit searching online for answers, but came with a few questions..
At startup, the truck does a a load 'whoosing' noise when driving. It does it under light load, and goes away when you step on it. I have power loss during this noise, and the both issues go away 5-10minutes in. Searching online it seems like the EBPV, but the truck does this pretty frequently at startup, even when ambient temps are +60'F. Occasionally, it will do the same at start up after sitting for ~1hr, but its primarily in the AM when I first get in and everything is at ambient.
If I leave the truck idling at first startup, it also sometimes goes into high idle after a minute or 2, again even when ambient temps are +60'F. It will kick back down by pressing the gas or brake.
I am interested in converting the EBPV into an exhaust brake at somepoint (seen the forums), but I would think I should resolve this issue first.

Thanks for the quick reply. It definetly sounds like it is coming from the engine compartment, near the area of the turbo. It only happens while driving cold, not at idle, so its difficult to diagnose on the ground. The noise sounds almost like a steam whistle, but not as high pitched or pronounced. Similar to someone saying "shhhh!" as loud as they can. I'm pretty confident its not a clogged exhaust nor a fan clutch.
I looked around and the only thing I found last night was the exhaust gasket between the left manifold and the pipe leading up to the turbo is leaking a little (you can feel it 2" away on your hand @ cold idle).
I don't think that is it, though I am not sure.
well i would definetly have it scanned for codes. if it's a sensor it should show up. ebp. shouldn't cause a driveability issue unless the exhaust is clogged (put hand over tail pipe) whooshing sound could be a boost leak check gauges and all boots to intercooler and turbo for a small leak. could even be a clutch fan noise and when it heats up alittle it goes away. hope this helps
