Rattling and vibration at low RPM, feels like its in wrong gear?

[Singhman]

Just bought a used 2006 Murano, and noticed that when i am just barely hitting the gas at slow speeds, i can feel vibration and hear rattling at certain. It sounds EXACTLY like a manual car that is in too high of a gear (almost like grinding). When i hit the gas a little more, the noise goes away, and the vibration is gone. i can replicate this anytime, and when i find that 'spot', and keep the gas pedal there to maintain those rpms, it will keep rattling and vibrating until i hit the gas a little (speed up), and then it totally goes away. Other than this, the car runs very smoothly at all other speeds. Any idea? Thanks

Hi, I have an 05 murano that does this exact thing. Did you ever find out the cause?

Thanks!
