    Engine Missing and hesitating at light throttle cruise speeds (2500 -3000 Rpms)

    Chevelle runs ok at low speeds and also at at full throttle.
    But when on the highway and you are at light throttle cruise speeds you can feel a periodic steady miss and slight hesitation. However increasing the throttle slightly will make it stop.
    The motor is an Edelbrock /Musi 555 efi ( Pro Flow XT) 2010 vintage.
    Any ideas what may be the cause and solution?
