Are the rpms supposed to drop that much when the engine is engaged/loaded by the transmission?

I had a similar issue with mine. I swapped out the motor mounts and that took care of most of it. Then replaced the power steering pump and that pretty much took care of the rest of it. That drop sounds normal. You can adjust the idle speed if you have the correct scan tool. I bumped mine up before I changed the mounts and pump and that helped. It now is set to run where the factory wants it to run.
