Bought a 2005 G35 Coupe 6MT a couple days ago with no issues. Yesterday the clutch started making a weird squealing noise making me think its the TOB but now the cars stalls when the clutch pedal is fully pressed down. Normally she idles at about 800 rpm but as the pedal goes in, it goes down significantly to the point of it stalling. Video linked.

 

Sounds like the TO bearing died, not exactly sure why it stalls the engine when you push the pedal. Sounds to me like a separate engine issue.

 

If the RPM's drop, then rebound, that's usually a vacuum leak. You might also have a lot of lag when you mash the pedal wide open (vehicle not moving transmission in neutral). If you have both issues then it's almost definitely a vacuum leak.

 

Yeah I just scanned my ECU and i need a camshaft position sensor so thats most likely why its stalling. and yeah i think the TOB is out. Thanks for the reply man.
