I'm a very attentive driver. Not only at the road but at the way my vehicle handles. Just last night, I noticed that my 2003 350z has began to rattle during acceleration and deceleration while in gear, in any gear. It only happens for about half a second to a second and then I can keep decelerating or accelerating without the noise happening. It only happens when I have gone from accelerating to decelerating or decelerating to accelerating. So I'll be speeding up one second and then I'll get off the throttle and the noise will occur for half a second and then the noise will fade and my car will keep decelerating like normal. Same goes for accelerating. It will happen once I accelerate and will happen for half a second and then the noise will be gone and I will keep on accelerating like nothing happened.

ALSO, this may be useful information. When the car is idling in neutral, the clutch rattles when the clutch is OUT. When pressed IN the noise stops and the car is quiet except for the engine noise, of course.

Anybody have an idea as to why my car is making this noise? Being a paranoid person if never good when driving a race car. Thanks guys!

It feels like if there was a worn engine mount when the engine shakes? It happened to me and the cause was the worn out stock dual mass flywheel.

does it sound like this? I had a couple noises. this was a misaligned pressure plate rubbing.... but in my description below sounds like what your having.. look for a Nissan specialist store, and ask them to take it around the block and maybe they can further help you out

i had some wierd sounds while acc and dec etc same problem like you had... aparently something broke off in the clutch and was rattling further back making that sound... ended up getting a whole clutch kit, bearings flywheel etc... so maybe a part of ur clutch is going.. TIME TO REPLACEEEEEE
