Answer
This could be quite an assortment of things. Your fuel distributor could be bad. You could have a faulty injector.  One of the many sensors could be malfunctioning. Throttle positioning sensor, Oxygen sensor, vacuum sensor, there are so many. The computer itself could be bad. If I had to guess I would say it is a bad injector.
