Well its very random. You can drive for a couple of K's and there will be no jitters at all. Then all of a sudden the cars starts bucking like a rodeo bull because its not getting constant fuel supply. Then it will die. If i keep starting the car, it eventually settles and i can drive it again. That process repeats itself.
Whether theres a lack of fuel or air to the plenum, i dont know. Could be something completely different.
