The main symptom this box was giving is a lope at idle, like someone fiddling with the rack lever and goosing it in a rhythmic cycle. A rough idle when cold is unlikely to be the EDS system, you can easily enough test the theory. Unplug the 2 pin connector on the big red solenoid on the back of the injection pump and start the car. Idle speed will be ~500-550. If your roughness continues, the EDS system has nothing to do with it and you have mechanical, glow plug, injection, or compression issues.
