2008 350z another engine rattle thread :( (with audio)
Hey Guys, need some help diagnosing this:
Started happening yesterday and seems like an intermittent/random timing for the rattle rather than a consistent predictable drone. RPMs above 3k seem to lessen or make it go away temporarily though could just be muffled by other noises. Difficult to trace origin of the sound so I'm not 100% sure if its engine itself or drive train.
*Update: Started it up and listened for about 2 mins. Sound seems to be coming from bottom of engine/drive train. The rattle occasionally turns into a whine like something is caught and straining, then RPMs will drop (giving it gas brings RPM up and stops whine). Engage/Disengage clutch in neutral has no affect.
*Update #2: Did oil change + filter but no affect. New video:

- Doesn't go away when engine is warm/hot.
- Higher RPMs seem to lessen it
- Have engine code: P2A00 (Air Fuel sensor)
- Oil change overdue and pressure seems lower than normal -will do oil change today when filter arrives
