[V8] Engine dying

[Dag Bøsterud]

I was out driving the other day, it was snowing quite heavily, and I had to drive very
slowly. I was taking a left turn, the engine was doing about 1000 rpm, and when
I pressed the accellerator again, the car felt VERY sluggish. I took my foot of the
accellerator again, the engine dropped to about 250 rpm, I tried to accellerate
once more, and at first the car wouldn't respond and felt sluggish. After what felt
like a decade, but was really only a couple of seconds it started to respond, 
and after that the car has been acting just fine.

...any ideas as to what might have happened?
