Rattling coming from engine bay?!?!

[Tko512iFX]

I have a rattling coming from my engine bay during normal driving. It only happens when I am off the gas and coasting. Has anyone dealt with an issue like this? It doesn't sound like the motor itself, there are no vibrations or anything like that, just a noise. Thanks in advance for the help! Car is at 94k and has never had a single issue (knock on wood) more than standard maintenance.

No i but at times i hear a rattling noise i start up a cold engine here and there. It last for about 2 seconds but the fx still drives nicely aftewards. Been hearing that noise here and there for the last 5 years.

Yeah I have had that same noise all along too! Bu now it makes that same noise when coasting or off the throttle. It quite annoying!!!

Timing chain rattle possibly? I heard timing chain tensioners going bad on the VQ35DE engines causing rattles and what not. Known problem on the maxima, murano, etc etc. Not sure about the 1st gen FX though....

That sounds like a deff possibility, any easy fix for something like this? Its not throwing any codes or anything its just kind of annoying at the moment.

Im also getting that rattle here and there now on cold startups. It lasts for 2 seconds and goes away. Then at idle I hear like I whinning noise throw it in neutral rev and it goes away for a few and comes back. Ill shut the car off completly and it sounds like a cat meowing I'm thinking it's my pulley anyone care to give me any info for those two problems.
