This happened today after degreasing and installing a speedomter cable. When driving the turbo will not boost the car like it use to. I could hear s noise that sounded like the turbo. I would have it floored and it would slowly accelerate after about 2200RPM as opposed to when it use to go pretty good after 2200 or so. I could feel a slight tug then it would cut out. So when accelerating after 2200RPM's it would start to go like normal then cut out. It is a 1979 300SD.
Thanks
David
