Cold Start Rough Engine Rumble
I have a 2012 G37 Coupe with 150K miles. Starting the car in the morning and then driving, the engine and exhaust has a rough rumble. It goes away after about 30 minutes of driving, then it is normal.
This is only occurs in cold weather months. Thought I would ask here and see if I can get understanding on this issue.
