I had this problem a couple of month's back. I was convinced the throttle body was the issue, so I soaked it in carb cleaner and then wiped it out - it helped, but didn't correct it. Finally I gave up and took it to my dad's mechanic about an hour and a half from here. He and dad spent the better part of an afternoon with it - new plugs, plug wires, and they adjusted the throttle cable. As it turned out, two of my plug wires were so old and brittle they broke when they took them off of the spark plug, the other six weren't as bad, but were bad enough. It was like a new car when I got it back.
The theory is that the plug wires were causing the issue. However, while he had it, I had him put a new fuel filter on it. It's easier to do on his lift than on my garage floor. So that could've been part of the problem as well.
If your's still has the original plugs and plug wires, I'd start there. Even if that doesn't fix it, it's money well spent.

Clean your idle air control and then reset as follows...
Depress the accelerator pedal slightly.
Start and run the engine for five seconds.
Turn the ignition OFF for ten seconds.
Restart the engine and check for proper idle operation.
