Why does your 89 dodge dynasty start but when you let off the gas it does not idle?

I had the same prob in a 90 Caravan when rats got up into the dash and chewed on some wires... the van started and ran as long as gas pedel was pushed down... Im not saying that rats chewed your wires but it might just be some of the wires that's under the dash are getting old like and falling apart on you...
