Surging D-jet 140-160

Hi Folks,
I finally wrapped up the mechanical part of my "71 142E refurbishing project, which included an M41 for BW35 swap and a valve and ring job. (Well, I also accomplished a bit of painting, patching, and modest beautification on the out and inside.) When I turned the key this morning it actually started, but it idled at around 2500 rpm and, when I backed off on the throttle cable and the throttle stop screw to get the idle down to where I could adjust the timing, it went into a surge mode. I haven't touched the idle adjustment screw yet since the whole FI setup worked perfectly before I started this project. I did replace the frayed throttle cable, the airfilter, the injector seals, and any hoses that looked suspicious; and I cleaned the throttle plate and its surroundings with carb cleaner. Before I start seriously to hunt for the cause of this problem; aside from the traditional vacuum leaks (Yes, Peter, I know, it's really air leaking into where there should be a vacuum.), does anyone have any suggestions where the best place is to start. BTW, could a bad brake booster enter into the equation? My brake failure light and buzzer came on, but that probably means that I need to do some more bleeding -- I hope.
