Ok this car has a mass air flow sensor (MAF). So what I would like you to do is unplug it and start it and see if it changes how it runs at all. Now keep in mind it will not have the throttle response but it if you lift the throttle slowly it should stay running. Get back to me on this I included a pic of the part so you know what you are looking for. Now if it changes how it runs before you go buy one I would use some Mass air flow sensor cleaner (no other cleaner should be used) and clean it. Now if it still runs the same but runs better unpluged then the MAF needs to be replaced. They usually cost around 85 dollars.
