vz hesitates during takeoff. coils???

[mattyr82]

hi all under med to heavy accelaration i can feel the car hesitating heaps, but only when taking off from the lights. at speed when u floor it it isnt noticeable. ive changed sparkplugs and all 4 o2 sensors, its got 133k on it so maybe coils im thinking. but also some one on here said something about gas vapour filters needing replacement every 20k and lpg computer recalibration ev 12 mths. what are ur thoughts?
