but, based on a round-the-block ride with the EHA disconnected if feels normal, like driving any other car. Before I disconnected it, it had a drag but it pulsed randomly-like I said, like very ligh toe tap on the brake-not at all constant.

I see what you are saying, the EHA creates the drag by reducing the fuel to the injectors-weird that mine seem improved. I guess the gas consumption will tell alot. I'm gonna drive it EHA-less tomorrow just to see what happens.

I have another symptom posted elsewhere manifested by a rough idle and one cylinder apparently not firing properly, so I suppose it's all inter-related.
