The engine begins to hesitate as soon as I press the accelerator. At idle and slightly beyond engine runs very smooth but as additional fuel is sent to be combusted engine bucks violently. Prior to two months ago engine ran very well but has sat on street for two months unused.

May be a fuel pressure problem, or a TPI sensor airflow or MAP sensor a scan will eliminate the possibility of a sensor fault and a fuel pressure test will show if there is a pump problem and don't forget to check for a blocked fuel filter as well.
