Well, if it only does it when it's cold then it's probably a fuel problem. Try cleaning the fuel injectors with some good cleaner first. As they age when they're cold injectors often don't work all that well. But I would also pressure test if fuel pump a week. Fuel pump will do the same thing when they're old and cold to take a while to build up pressure
