I have a problem. Ever since the weather has been cold her in Georgia I have been having a problem when my 370Z gets going. Trying to figure out how to explain:
If the weather is cold outside and I first start my 370 up in the morning, the RPM's will not go below 2 or 3K when in Neutral. The RPM are moving as expected while shifting or in gear, but when I stop at a stop sign or red light and have the car in Neutral the RPM's will go up. This usually goes away after the car warms up, but today I drove it for 15 min and it still stayed at 2K RPM when in neutral.

Any suggestions? I am taking it in to the dealership on Friday, but wanted everyone's opinion.

Also, my check engine light has come on twice and both times the computer read out was cylinder misfire.

17K miles currently on car.
