Ok i just went outside and checked. 4th line down does look like its 400rpm.
That's very odd since most GS idles around 550-650 rpm.
Perhaps its time to clean out the idle control valve. It gets very dirty and not too many people clean it. It made a tremendous difference on my car. Idle was noticeably smoother too.

scroll down to the post I made. I provided pictures.
You can open it to check. But if it's dirty and you want to clean it, take out the throttle body and clean everything. You can probably use a toothpick to clean out the hole if you don't want to take out the TB, but I did everything at once.
Most people are not aware that this exists on our car. Most cars have their throttle plate open just a bit at idle so air can go in. On the GS however, we have these little holes instead.
