car idles high in neutral and park and surges in drive to where it almost won't stop on 1998 Oldsmobile Regency

My car started out dying even while in motion. I was able to put it in neutral and start it right back up. Now, it surges very fast in drive and I almost can't stop it, actually having to drop it into neutral to slow it down. But when in neutral and park it revs so high it sounds like it might explode. Could something be wrong with the throttle body? Or would this be an air intake control issue?
