You need to pull codes.

I wouldnt be looking for vacuum leaks, only reason I would look for this though would be for the rough idle but in your case it is something else.

The computer is recognizing a problem and is having the engine put in more fuel to take care of the chance of blowing the engine.

Pull some codes and post them up here and then we can further diagnose it.
