Sounds like your idle stabilizer may be going on the fritz. There is one
quick an easy test to isolate whether it is the stabilizer or not.

Start you engine, let it warm up thoroughly. Check the engines habits one
last time. Shut it down, disconnect the idle stabilizer wire where it
connects to the end of the idle stabilizer. Start the engine. If it idles
smoothly, change the idle stabilizer.

If it does not idle smoothly, shut down, reconnect the wire, and look for
another problem. You may be having trouble with the O2 sensor, but I am not
versed enough on it to offer advise. Some of the other folk on the list have
a lot more experience. perhaps someone will address the alternatives.
