Not necessarly, it could be a plugged IAC or a dirty throttle body, do you have a check engine light on? If so get code read, find out what it is and repair that first.

Maf sensor should cause your check engine light to come on. But if no check engine light I would consider dirty/faulty idle air control valve or dirty throttle plate. The iac will not always thro a check engine light code.
