Car vibrate when stop at light

The RPM is a bit EDITED LOWER than 1000 RPM. I have the AUTO transmission. It don’t happen all the time. The vibration is at the steering wheel. Kindda like engine vibrating I guess. I do not notice any extra noise but I have to open my window to examine it. The mileage seems unchanged. I forgot when the vibration happens but MAYBE the last 10k or 20k.

It do not vibrate when I put it in neutral but I THINK I can hear it in the engine.

Vibrate physically.

Thanks
