Hello, the rpm fluctuates when stop at signal. Sometimes it stalls and need to restart it.

Good afternoon,

Is the check engine light on? If it is, do you know the code as it will help narrow the area of failure.

I would start by cleaning the throttle body as dirt and carbon can cause this issue.
