weird noise under acceleration
HELP!!
I have a 2006 6mt and I recently started noticing a weird noise that drives me crazy. It only happens for about 0.5-1 second at the beginning of every acceleration and it sounds like shaking an empty beer can with rocks in it. The noise comes and goes and it's not too loud. I barely notice it when I drive to work in the morning but definitely hear it more when the engine is hot. So I think it's temperature dependent. Anyone has experienced this? I drove 140 miles to see a dealer yesterday and they couldn't tell me anything. Any ideas? Thanks in advance.

I have the exact same issue, it just started a couple of weeks ago. I have an Automatic 2007 G35 sedan; here's exactly my problem:
Though it fluctuates, whenever I reach approximately 3000 rpm, I hear a rattling or almost knocking-like noise from the dashboard, driver's side. I have heard maybe something is loose? It speeds up as I increase RPM. For the first time since this happened yesterday I got to nearly 5500 RPM with no noise at all, but then it came back again.
Any ideas? It's driving me nuts and I've been driving slowly ever since so I don't stray too far past 3000 RPM. Thanks

I guess I just need to live with it. It's hard to put up with noise like that in a luxury brand like Infiniti.

I'd begin by checking my oil level. If it were an o2 sensor it would be throwing a code and your "Check Engine Soon" warning would appear on your dash. Then I'd want to find out if my timing was correct at the RPMs you described. The bearing you mentioned is called a "Throwout Bearing" and they do dry out but, it would be making a major noise all the time the car is running....everything from a chatter to a squeel. Converters make a noise as do exhaust systems (mufflers) when they broken and lose. You can tell by banging on the exhaust while she's up in the air. (rack)

just some updates on this issue:
I took it to a garage yesterday and the mechanic checked all heat shields underneath the car since they tend to rattle a lot. but everything was fine on my car. Then I talked to him about a second problem(more "play" on the clutch pedal) that I recently noticed and he found a TSB which relates both problems.
Here's the clutch problem: When I pushed the clutch pedal with my hand before, it only went down as much as a click without me exerting too much force. now, it goes down at least an inch. This symptom aligns with the TSB which is on the pivot ball for the clutch fork. It might have partially collapsed or snapped. The TSB also causes a rattle, but I'm not sure if it's the same noise I'm hearing.

dunno if I have the same problem but I notice it two times (both have to do with the clutch but also might just be because gas+clutch=vibration as it's a no-load quick revving situation) when I take off I sometimes hear it, and sometimes when I'm pushing the clutch in and hitting the gas to rev match and downgear to engine break or whatever I hear it.
