Is your check engine light on? It should be fuel injected. Which means you can't really do a whole lot. Check your vacum lines. My books say you can's adjust the idle at all on these. I know on a Chevy you can sometimes turn the TPS on it's mounting screws to get it adjusted right. But I don't see one at all on these.
When was the last time you did a tune up?

One important thing DON'T MESS WITH THE IDLE SCREW!!!!! I can't stress that enough. The fuel injection system is run with that at a specific spot, so messing with it makes it really hard to get everything back in sych again (speaking from experience, did it before someone told me not to).
It should idle somewhere around 700-850RPM, do you have a tach? When was the last time a tune up was done on it?
Will it just not idle, or does it do this all the time?
