Info needed.....

I have a 94 F350 OBS PSD, when my OBS sits overnight and I take off in the morning, it doesn't seem like it wants to go... feels like it is missing, doesn't want to take off very well, after driving for a few minutes, seems like it cleans out so to speak.... I've changed the oil and filter plus the fuel filter, seemed to run better this morning, but later tonight it was back at it again..
Any thoughts.....

I'm thinking it's your EBPV. It activates when the air temp, and water temp are cold. When it gets to a stable temp, (Normal operating temp), it will open back up.

It's your EBPV....Mine did it yesterday morning and it was like 45 F here. It's part of the turbo just after the Wastegate in the exhaust tract, right where the downpipe bolts to the turbo. You CAN unplug the plug that actuates it (located on the turbo), or just deal with it. I'm just dealing with mine until Apr 15th....I have a WG and EBPV delete exhaust housing waiting to go in.

Nothing is 'wrong' with your truck. The EBPV closes, causing the truck to work harder to aid in warmup. It should open when you get on the throttle. If it isn't, it's sticking probably b/c of soot buildup in that area.

Yes...but your better off just unplugging it for right now. if/when your ready for a turbo upgrade, you can either gut it out of there or get a EBPV delete adapter.

if your truck feels like its skipping in the morning cold is because it very well may be , it is very possible to have a couple injectors sticking cold ,and once warm will smooth out and run fine , the ebp valve can cause it to be low on power but when you wide open throttle it it should open up ,as far as the injectors go , not alot you can do for the skip cold , you can try to clean that may elp but the damage has already been done , as long as it smooths out warm ,would not be concerned
