Greetings -
I was headed to the beach on the interstate last week-end, going about 60,
not accelerating or decelerating but maintaining my speed, when suddenly the
van bucked pretty severly.  It immediately went back to normal and nothing
extraordinary happened for the balance of the trip (45 minutes or so),
except for the acceleration of my heart rate to 190 bpm.  I may have let off
on the accelerator slightly without realizing it and the bucking was my
pushing back down on it (some kind of torque thing??), but I don't think so
and this has never happened before.  It happened once again the next day on
my return trip.  Bucking is the only way I can think of to describe this
event; it was one brief, sharp jerk of the engine, then onward as if nothing
happened.   Any ideas out there?

Thanks!
