either the compressor or the fan kicking on. Take it back and get that adjusted.

Ditto.. Most likley the compressor. Could be the belt or the compressor it's self

May also be the "bucking" that most of us experience due to our clutch/motor mounts which will be much worse when the a/c is on. If you do a search you'll find a bunch of threads on this problem.
