I have the same problem, but it does not matter if engine is hot or cold. It happened even before any mods. Truck only has 55k miles, 2001 7.3L Auto-Trans.

I have noticed that other people have wrote similar threads, but no one has giving a fix answer!! I can not believe that?

Would like to know the fix.
