Sounds like throttle arm to me too.
I'm assuming you didn't remove the top of the pump at all, and you definitely didn't touch the governor? If so, only thing it can really be is the throttle arm. The ECU-controlled part of the pump controls timing, so if something's been disturbed on the throttle arm to affect fuelling at idle the ECU will be reading default values which will be mechanically out if the arm's out by a spline or two.
Just my thoughts anyway. Rip it off and fit a mechanical pump ftw.
