Should the rpm be on zero while driving sitting idle
My car has an automatic transmission.

On these type of issues where the cluster sometimes do erratic things you can do a battery cable reset by disconnecting the battery cables and touching them together for three minutes and then reconnecting them to the battery. When you do this you will need to reset the radio using a code you should get from dealer before disconnecting the cables so you can turn back on the radio.
