hey guys, I just bought a 03' G35(350GT) from japanese import car dealer last week. I was driving my car tonight and I felt it have a slight vibration under my feet near the gas/brake pedals (actually i can sense it from the gas pedal) while accelerate and idle. Also you can hear a slight sequential noise come under from the chassis when the car idle. I never drive 350GT before so not sure if it is normal. Any suggestion? Thanks a lot.
