Hi, I searched but couldn't find anything exactly like my rattle.

I have a 2005 Enthusiast 350z automatic and it has a rattle in the passenger side engine bay area.
It only rattles at ~ 1.2 – 1.5 rpm (all gears), and only when the engine is cold.
After about 20 minutes into a trip, the rattle goes away.

Any ideas of what this could be?

Thanks!

 

Its obviously no emergency as you can tell I haven't bumped this in a while.

Id just really like some ideas on this so I can be informed when I go to the dealership.

Thanks!

 

Not much help here but...that is the opposite of my rattle.....I have one that starts at around 3k in all gears (gets faster as rps go up). Initially thought it was engine related but took it to the dealer and they say its most likely form the dash area. It's going in on Wednesday so they can look into it (as well as do the cltch recall). I'll let you knwo what they find....in case it helps you..
