Did you have the leads off? If so did you replace them in the right places? 2 it just may be a lead? As i had kind of the same prob a while back id try to put the foot down and she would splutter and jolt,(you may think this is a joke) i rang a very good mate of mine who works for summit holden on my mobile and he told me to rev it as he listend to my car via a nokia mobile phone, from the other end of the phone beleive it or not he said i had a stuffed lead,and to top it off he said it would be the longest or the shortest of the six (he was rite on it was the shortest lead(i replaced 1 lead and the car was back to norm) not that this may be your prob? But you never know untill you give it a go cheeers and good luck
