I have an 05 G35x. Everytime i start the car up it sounds fine but when I put it into drive there is a chattering sound that it makes and usually goes away when i get up to 10-15 mph. Anyone have any idea what it could be ?

 

It's really hard to know without knowing what maintenance and mileage u have on the car.
Best to take it to a reputable mechanic.
Check oil level
Check belts

 

Its sc chatter.
No really what irishsig said

 

Its not any belts and i just got the oil changed.
