It would most likely be an injector not functioning properly. With the puff of white smoke indicating the fuel is dripping instead of atomizing at the point of injection. The other possibility would be a cylinder with low compression. Usually that will cause a dead miss but I have seen them be intermittent at first. I would try to crack the lines at the injectors individually while its running and see if I could determine which injector is faulty. Then have that injector tested for the problem.
