Why does my engine hesitates when I accelerate?
A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.

A clogged air filter starves an engine of much-needed air, skewing the air/fuel mixture that affects acceleration.

Why does my Subaru have a low power response?
After explaining problem to mech he said it was either the fuel pressure regulator or the fuel filter, I took the opportunity to replace spark plugs, air filter, oil, oil filter, and a very dirty fuel filter (which I believe was the culprit in my case), and of course a very expensive O2 sensor.
