2008 g35s with 9 miles having light vibrations at stop lights and even in N

[blackberrycubed]

Hi Guys,

I have a 2008 G35S with only 9k miles on the ODO. I started using the German Castrol synthetic since the car hit 5k. I just did an oil change 100 miles ago with the same oil.

I am noticing that the car tends to vibrate while I am stopped at a light, regardless of whether the ac is on or not. If I move it N it does the same thing. Any one else experiencing this? Could this be bad gas? or Carbon build up?

I was thinking of adding a bottle of Sea Foam to the remaining half tank of gas... What do you guys think? Vibrations are not bad and you have to pay attention to fee them but they are there. Almost feels like a cough.

Please Advice!Thanksk

I think I'd take it to the dealer and tell them to fix it under the warranty.

What octane are you using? What is the idle rpm? Is it steady rpm at idle?

open up your hood and check those belts. i know that sounds crazy, but the loaner that the dealer gave me has 7k miles and is a 2008 g35 which sounds like the belts are already warn. it is far squeakier and louder running than my 2004 coupe (and i dont mean when you press the gas to the floor, i mean at idle in park).
