Peter, I had this RPM hunting problem on my '88Gl with the 2.1L engine.

First I replaced the O2 sensor, then with the engine warm, I shut it
down, disconnected the idle stabilized, started it up, adjusted the idle
speed, shut it down, reconnected idle stabilizer, started up again.

No more problem.
