My 95 SE does that when it's cold, in fact my 99 SE does it to. It seems normal to me since it lasts for 20 sec and then just the normal ruff idel of a car with a sticky IAC. But the 99 has a clean IAC and does it too. And my 92 Topaz did it, so it seems normal. It's just what it does when it starts up from a cold start. It never happens when the car is warm or it's above 55 deg. F.
