It sounds like your engines Idle Air Control or IAC is acting up. This device increases or decreases airflow into the throttle body to maintain desired idle speed. The idle stop screw may need to be adjusted as well. A qualified technician, such as one from YourMechanic can easily resolve the engine idle issue.
