I have had a couple of FI cars that never ran quite right at low speeds. They tended to buck instead of running smoothly. I believe they also had one other symptom in common. If you ran the engine at idle and slowly depressed the throttle, they would drop in RPM quite noticeably just off idle (I assume as the throttle valve switch came off the idle contact) and then recover with additional throttle. Do any of you have these symptoms? If so, I believe they may be caused by a presure sensor which is causing the FI to run too lean. I would like to look into a solution for this, but I'd like to know how common it is first. Of course I'm assuming that compression, ignition timing, and valve adjustment are all correct first.
