Hi all. I posted this a while ago but never really got to the bottom of this and it is getting worse. This 2003 225HP HPDI has been flawless until about 9 months ago. When I would put it into gear it would stall 20% of the time originally now it is more like 90% of the time. If I give it some gas when putting it into gear it does not stall. Once in gear and running it runs like a champ. It is the actual shifting into gear that knocks it out.
I've done a little research but have not found anything that points me where to look other than taking it to the dealer (1.5 hour drive). I changed the plugs hoping this would do it but this made no difference.
Any thoughts or suggestions would be greatly appreciated.
