    First step - have the check engine light or stored fault codes scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' for more assistance.

    Possible Causes of Engine Hesitation or Stumble:

    Dirty fuel injectors (cleaning the injectors often fixes this)
    Dirty air filter (change filter)
    Dirty / clogged fuel filter (change filter)
    Bad MAP (manifold absolute pressure) sensor
    Bad TPS (throttle position) sensor
    Bad or dirty MAF (mass airflow) sensor
    Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
    Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
    Bad gasoline (fuel contaminated with water or too much alcohol)

    Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

    Dirty or worn spark plugs
    Bad plug wires
    Weak ignition coil
    Wet plug wires
