My car won't idle on 2002 Ford Escort

When I go to stop it dies and when I go slow it will die
and just sitting and idling it won't idle

It could be so many things its hard to speculate without being able to d basic diagnostic tests. Is the Check Engine Light on? If so codes stored in the computer of your car would indicate where the problem is. I would suspect there is a vacuum leak or the idle air control valve has failed.
