I have a 94 F-250 7.3IDI 4X4 E4OD 155K miles. When I start the truck I have to press the accelerator a little and then it starts fine. Then when I depress the accelerator and lift quickly it immediately shuts off. It doesn’t matter if I’m going slow or what. Now if I gently and slowly lift off the accelerator it will stay running. When it does stall I can throw it in neutral and it immediately starts. Other than that the truck runs great. Any information on what causes this and how to fix it would be greatly appreciated.
What are your rpms at idle? Does it only do it when the truck is cold? Is your cold idle and cold timing advance working?

Everything seems to be normal. When I first start the truck (cold) the high speed idle solenoid kicks on and once the truck warms up the solenoid closes and idles just as good as it ever has. I would have to check again but off the top of my head I think around 1,000 maybe slightly higher. I have no engine lights or anything else on the dash saying that there is a problem. I can be at a stop and stand on the accelerator and the truck takes off, it’s just the problem of slowing down.
For those of you that have replied so far thank you very much, and hope yall can help me some more.
I borrowed this from "The Dieselmanns Page". OkieGringo
Engine stalls at stops or when depressing clutch
Stalls returning to idle after snapping throttle open. Injection pump problem caused by poor quality or contaminated fuel. Check for presence of water in the fuel--removal of the injection pump governor cover may be necessary to find contamination, but is not advisable unless you have experience. Check idle speed setting and injection pump timing, as well as cold timing advance--timing should advance at least 2 degrees with 12 volts applied to the rear solenoid terminal. Adding Stanadyne's All Season Diesel Fuel Conditioner may cure this problem, but if it persists, or if there is no cold advance, replace the injection pump. Recommend that the Stanadyne All Season Fuel Conditioner be used periodically to prolong injection pump life.
