Sounds like you have a problem with you idle stabilization circuit.
Check the idle stabilizer valve (sticking or otherwise not operating
properly--clean or replace), the control unit(biggest relay under dash,
and/or the thermosensor for the idle stabilization circuit. I had a
problem like this a couple of years ago and it turned out to be a bad
connection at the thermosensor (the front most single-lead thermosensor
on the lower side of head). If you do have a bad connection or bad
thermosensor, you must kill the engine and then restart before it will
correct itself--at least that was my experience.

Hope this helps,
