Hello. Problems such as these can be caused by many things. Anything ranging from a bad vacuum leak, to a faulty idle air control valve will cause symptoms such as these. As engine performance problems can many times be hard to diagnose, I would recommend having the vehicle looked at by a professional technician, such as one from YourMechanic, to ensure that the correct diagnosis and repair is made.
