After I start it up it is idling high, until I put it in gear. Then it stops. Any ideas ?

It is supposed to idle high for a minute or so after a cold start. It should settle down after a minute or so (if you wait that long) if you give the pedal a quick stab. Otherwise, just driving it moves the throttle enough to let it lower on it's own.
