After wanting one for years, I finally pulled the trigger on a 2013 G37x sedan a couple of weeks ago. I'm really impressed with the overall performance, but I've noticed some vibration when stopped at a light (in drive), and the idle speed seems a bit low. The vibrations aren't excessive, but more than I had expected for an Infiniti. I was wondering what the normal idle speed is for these vehicles when in drive, and if it's normal to feel some vibration. The vibrations dissapate when I put it into park and the RPMs increase slightly.
Here's a picture of the tach when in drive for reference. Thanks!
I would call that low, do you have the history on the car? And if so did someone perform a recent spark plug change and they cleaned the butterfly inside throttle body? You will have to take to Infiniti to get that fixed it has to relearn.
Thanks for the reply! Unfortunately, I don't have the service records, so I'm not sure if the plugs were ever changed. The car only has 20K miles on it, so it's somewhat doubtful, but I think I'll schedule an appointment with Infiniti to have it looked at while it's still under warranty.
