I took my D to a garage yesterday to find out where my all my anti freeze is leaking from. While it was in the shop i asked them to diagnois why she was idling so high. There answer today is, that my spark plugs are arcing and my fuel injection needs to be purged? What does fuel injection needs to be purged mean?
