G35 coupe makes rattle noise when cold start and sometimes while driving
Hey guys I’m new here and couldn’t find a thread about this issue. I have a 05 coupe rev up it has a manual transmission and 125k miles. The car makes this rattle noise every time I cold start it. And lately I can hear it a couple seconds when I let off the accelerator at around 3k rpm. The noise seems to be coming from the engine bae. I haven’t found any helpful information on this just a bunch of other people with the same issue and no fix.

There could be multiple causes of your rattling. Have you gone in the engine bay or under the car yet and checked for loose components? I'll take a shot in the dark here and say your catalytic converter heat shields might be starting to come apart. It's a common problem.

Good suggestion. I forgot about that since mine has had the "marbles in the transmission" since it was brand new, and I'm immune to the noise now.
