I had almost the same problem when I replaced the timing belt
on an old over head cam Fiat. I was 1 tooth off (don't remember

Have you tried less gas on acceleration?
Do you have a Map or Maf sensor?
A Map sensor will over-react if placed too close to the
throttle plate ( corrections..opinions welcome ).
