IDLE LOPING

What would cause the batt. light to come on AND the car car to "lope" when idling on a 1989 grand marquis? It goes from 600 rpm to

1000 rpm when idling in two seconds, continuously. Is this the voltage regulator? :? HELP!

The battery light comes on because the engine rpm drops too low to turn the alternator fast enough to put out sufficient voltage. The problem is most likely a vacuum hose.
