Get a can of GOOD carb cleaner, no cheapo stuff. Hit the idle air control motor, and passages. Careful on the gasket, but go ahead and reuse it. Next up is the mass air flow sensor. CAREFUL cleaning here too. You'll see a small thing that looks like a resistor hanging in there. Clean that real good. If that fixes it, great. If it helps it out a bit, but doesn't cure it, get a different mass air sensor.

I would have guessed coolant temp sensor, but you already replaced that. Make sure the plug on it is OK, and make sure that there isn't another one. Some of those engines had 1 for the gauges, and another for the computer. Check it out.

Good Luck!
