Engine Performance problem
2000 Chrysler Neon 4 cyl Two Wheel Drive Automatic 90000k miles

from stop position, car is very slow to accelerate, put pedal to floor little acceleration gradually gets into another gear once engine rev comes up, once you get to 60k it seems to be better

sometimes it will all of a sudden rev & jerk forward on its own
