Sounds like the classic 3k hesitation. Do a search.

By running an extra engine ground (or two ) I reduced the occurrence on mine, but there is plenty of info on that (look at the FAQs).

Some people thought that the hesitation could be caused by the voltage transition to the fuel pump set by the fuel pump resistor. If that was actually true, I'd suppose rewiring the fuel pump would fix it. I'm rewiring mine during my rebuild process, so we'll see if mine disappears.
