Why did the FD need rebuilding? Based on the circumstances, it sounds like the system just needed to be tuned and that can be done without a total FD rebuild.

The rebuilt FDs are probably set to flow equal amounts to each injector, but injectors don't flow the same. The FD really needs to be tuned to the injector set and that matched flow needs to work with the EHA and idle adjustment in a way that the computer can control and the window is small.

A half turn at the FD will require about a 1/4 turn at the EHA to compensate which will require a turn or more at the idle screw. Miss one of those adjustments and the car will not start.

In short, don't get down on the FD rebuilders.
