I was recently was outside running my 98 Grand Prix GTP while scraping the ice off and all of sudden the car started slowly shaking and rumbling on its own for a couple of seconds. Any thoughts?

Bad Ground.
An Erratic Misfire.
A slight bit of ice flowing through the gasline.
Clogged air filter.
Too many electronics ( Rear Def & Heater on high, radio, etc ) turned on before car is warmed up.

Defroster on? Did the A/C compressor engage? Though you have it on hot and it is cold outside, the A/C would still be active and try to compress when needed, especially if your freon is low.
