could be somthing to do with the ignition, maybe it cant hold a spark, or its depriving itself of fuel, could be a number of things, if you can give a more accurate detail of whats happening, i could try to point you in the right direction.
if not then first check for spark then check for fuel problems, try getting injector cleaner then work your way back

My Haynes repair manual says
#1. loose or damaged wire harness conections at distributor, coil or alternator.
#2. Intake manifold vacum leaks. Make sure all mounting bolts/nuts are tight and all vacum hoses connected to the manifold
are attached properly and in good condition.
#3. Insufficient fuel pressure.
#4. Fuel injection or engine control systems malfunction.
you also might want to check and make sure your air filter isn't getting clogged.
Hope this helps??

IAC. You need to clean it with some carb cleaner. That would be an easy and inexpensive place to start.

Let me find something...

Here's what I was looking for. Go down through the post and you will find a pic of what you need to clean.

Ok, here's another link that will help step by step and also a pic that will show you where the IAC is on your engine. It's easy, it is bolted to the higest point under your hood. Find the horse.

EDIT: You will need an extension to get to that bottom bolt.
