1994 Acura Legend V6 Wheel Drive Type unknown Automatic 130000 miles

When vehicle is on and in park it occassionally revs up and down. One time it even shut off while doing this. Any ideas?

When was the last major tune-up?

Check the idle air control valve or speed controller to include the throttle position sensor. Also might want to check fuel pressure with a gauge.
