06' Sentra Idle RPMs
 

Hi all,
Can somebody tell me what is supposed to be normal rpms for my 06 Sentra.
When starting from cold(after night) and in park it is 1200-1500 - Is this normal??
When starting after a stop of few minutes and in park it is 1000-1100 - Is this normal??

After that when I switch to drive - it drops below 750.

After that its smooth all around. But I am concerned at the idle park RPM?

Also, is sentra interior loud compared to other cars in the same range( Civic, Corrolla etc.)

Thanks in advance for your input
