Partial throttle bog
1999 e350 7.3 powerstroke van. So the truck has a funky issue. At partial throttle (id say 1/3 throttle) it has this weird bog. The truck makes a loud moaning/gurgling sound and loses power. Once you put the pedal to the floor the truck snaps out of it and runs perfect. If i drive around flat footing it all day id never notice the problem, but thats a little excessive haha. Its cold here in new york and the problem is definitely worse while the motors warming up. Its really annoying when cruising at 50-55 because it will get caught in that bog and I’ll have to constantly floor it and then let it coast.
Im running antigel in the fuel
new fuel filter/water seperator
new air filters
im not sure what to do next.

Do vans have the warm up butterfly valve in the exhaust after the turbo?
If so when it happens does the exhaust sound like it is hissing and is restricted? Could try wiring it open and see if it happens still.

They do, they don't have a waste gate though.

The actuator has some O-rings in it that will leak over time and many guys delete it. Deleting it is a split camp, some advocate for it, others against it because it does help warm a cold engine in the colder northern temps. And some use it as for engine brake.

Wiring it open as a test wont hurt anything though. Even some in cold areas delete it because it will constantly close and open while going down
the road.
Gotta try it and see if it helps first, this is just a guess at the symptoms.
