I moved your post to its own thread so you will get a little more attention.

Mine idles at 650. 900 is a little high and might partly explain why it shakes your car when you shift into forward or reverse at a stop.

Let'* see what the experts say about high idle.

Here is the target idle speed. 900 is about right depending on the engine temp. If up to operating temp 900 is a tad high.

In park/neutral at 200degrees F it is about 800-850 rpm
and in gear at 200degrees F it is about 700-750 rpm

also gauges are not accurate at all, I've found my RPMs to be off by 100-200 at idle and temp may read over 200 but it under 185, the most accurate way is to use a scanner
