this sounds like your idle air control valve is bad or stuck to far open. any sort of vacuum leak will cause a higher than normal idle and gm used an I.A.C valve located in the intake manifold to open and allow air in to control the idle. this is where i would start.
I would also inspect all the rubber vacuum hoses as this would cause the same simptoms. and at 15 years old there is a chance that there could be a leak there also

Turn the idle down or set the timing!

If I'm not mistaking this engine has a carburator, so should be easy to ajust by a mechanic.
