Hi Debra:
what engine is in this? it could be a few things a vacuum leak from a split vacuum hose. It could be a bad idle control valve it could have a skewed TP sensor and it's cauing a high idle. any check engine light on? if so stop by one of the big box auto parts stores and have it scanned for codes it could be a clue as to what the issue here is. that is where I would start looking.
Good luck :-}
