Hi and thanks for using 2CarPros.
It sounds like the idle air control valve is bad. It is responsible for maintaining the engine idle speed. When they go bad, the engine idle will lope up and down and often times stall.
The component is located on the throttle body. I attached a picture.
Here is link that shows in general how one is replaced:
Here are the directions specific to your vehicle for replacement:
The Idle Air Control (IAC) motor (3) is located on the side of the throttle body.
1. Remove air resonator box at throttle body.
2. Disconnect electrical connector from IAC motor.
3. Remove two mounting bolts (screws).
4. Remove IAC motor from throttle body.
1. Install IAC motor to throttle body.
2. Install and tighten two mounting bolts (screws) to 7 Nm (60 in. lbs.) torque.
3. Install electrical connector.
4. Install air resonator to throttle body.
Let me know if this helps.
