I seem to remember, in a thread a few months back, that someone mentioned a possible cause of surging to be unburnt hydrocarbons being reintroduced to the air intake via the EGR. Not sure if that was a true cause or what, but I had the start of some minor (and random) surging just prior to disabling the EGR on my truck.

Anyway, just a thought to throw out there.
