Hesitation on take off

So many things could cause this type of problem but it is hard to gues without being able to experience the problem first hand or at least do some basic diagnostic tests. An ignition system that was had a component breaking down, (spark plug, plug wire, ignition coil) could cause this, a fuel injection engine that was getting a false sensor signal from an air flow meter or a vacuum leak at an intake manifold could also cause this experience. I am afraid some basic tests need to be done first.
