Check the gasket between the TBI unit and that intake manifold for starters. You might check the idle control valve too. I do suspect a large vacum leak. With fuel injection you can have a pretty big one and still run okay most of the time except for idle problems.

If I'm correct that is the plastic intake manifold. If it is, try spraying around the base of the maniflod with carb cleaner if you notice a distance it is possible that the entire manifold is warped.
