Q: Lately my car has been revving itself up and down when I 1st turn it on. on 2005 Mercedes-Benz C230

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The RPM goes up and down roughly between 30-40 rpms until I start driving it This happens in the morning and goes away as soon as I begin to drive...Does something need to be replaced?
