Hesitation can be caused by many things certainly fuel supply/injection, computer controls (sensor inputs and controlling outputs), and ignition.
I would take a close look at the spark plugs and plug wires. The ignition system is likely to be the culprit.
If the throttle venturi/butterfly area hasn't been cleaned in a while it too could cause a problem but I would start looking at the ignition first.
