Hi. This sounds like there maybe a loose or broken vacuum line going to the engine or intake. There is also a possibility that the mass air flow sensor is bad or very dirty causing your issue. The tubengine from the air filter book to the intake could also have a leak in it as well. I have also seen that a bad idle air control valve can cause this problem as well. I suggest you have a certified tech from yourmechanic come and diagnosis your car.
