Hi Folks, I'm a newbie to owning a "D", and a newbie to your group. As an electrical engineer I'm hoping maybe my experience can help someone in those areas - but for now I'm the one looking for some mechanical help. My D is having "Deceleration" problems. When cold or hot, it starts fine, although the idle hunts slightly. The acceleration is smooth and powerful, however on deceleration it "kicks" and feels very choppy. I suspect a vacuum related problem, but have no real proof of that - only that it mimicks the symptoms of a car from years before. Any suggestions before I seek out a local pro?
