98 GS400 - Idle Speed Adjustment
When I first start my car in the morning (it usually about 35 degrees outside), she idles at about 11 hundred rpms and doesn't settle down to 8 hundred rps til I've driven her for about 20 min.
Question: Is this normal?
She didn't start doing this til i tightened down one of my spark plugs and cleaned the throttle body with carb cleaner.

I'm wondering the same thing...just changed all the plugs, cleaned the throttle body, didn't touch the MAF. Did all this when I rebuilt the starter.
I don't remember the car idling that high before the maintenance was done. Mine does settle down to a steady 800rpms in about 5 min after startup though. Also a 98 GS400.
Thoughts anyone?

Here's a picture from the non-VVT-i service manual that may be of help. It's not exactly the same as ours, but it's the same general idea.
Glad to hear.
