Actually, my DGEV has exactly the same issue. (1) I'm now using a stronger spring from Ace Hardware. You don't want a spring so strong that your leg will feel like lead on a longer drive. (2) I've sprayed the rear area of the carb with aerosol brake cleaner, then sprayed with an aerosol light oil, and that seems to have worked for several months now. I have a $30 tach, so I don't need to rely on on ear to tell this, but the idle would go to maybe 1100 rpm instead of its usual 900 rpm when this happened, and it would "diesel" when I shut off the engine. It was not anything with the accelerator cable or my aftermarket cruise control cable either.
