dam im clueless, could be a lot of things,could be a bad coil, could be a bad starter, could be throtle position sensor, ive noticed my uncle working on a lot of cars that have the same problem, couple of times it was the TPS, the other week my friends Civic Si 2000, had the same problem, one of his plugs was miss firing and he needed a new TPS, so it might be the same thing, its hard to tell from what you have writen, you could have been a lil more clear...
