Sounds typical of a vacuum leak. If any air sneaks in that doesn't go through the mass air flow sensor, the Engine Computer won't know about and it won't command the right amount of fuel to go with it. Also check the air tube between the mass air flow sensor and throttle body. There can't be any leaks in that tube.
