My autothrottle does not go to idle on touchdown.  Is this normal?

No. It's not normal if the throttle is not going to idle on touchdown.

Mine works fine though, so if yours doesn't, you have a problem. After takeoff, when you turn the Autothrottle ON, set the throttle lever on your joystick/controller to idle, and see if that fixes your problem.
