You may want to look at a couple of things. First connect a vacuum gage to see what your engines vacuum is, if you have low vacuum then you have a vacuum leak that needs to be tracked down. If you have good vacuum then check out the idle air control valve, you may be able to clean the valve and free it up or if that doesn't work you may look at replacing it. Good Luck.
