What's the "rest of the story"? scar face 10-26-2004, 03:47 PM Both hot and cold more hot I have used stanadyne fuel additive 34000 miles started about 1000 ago chuntag95 10-26-2004, 05:30 PM Probably the fuel pressure regulator. Mine does the same thing. Mine hasn't gotten bad enough for them to replace it either. I think it is more of a I haven't found a good enough tech that can tell I'm right yet.http://www.dieselplace.com/forum/smileys/smiley18.gif scar face 10-26-2004, 06:20 PM Thankes I think you are right they think I am to critical I run a diesel rebuild shop and know a little bit about what I am talking about. NWDmax 10-26-2004, 07:26 PM I'm with Chuntag on this one. Mine runs rough when cold (big lope see the oil pressure bounce with it) and when warm will do it too but just not as bad.
