Fellow 350z owners. My engine fluttered to a complete stop today...only has 29000 miles on it. I'm lucky i got enough juice out of it to get in back to my house. It was a sketchy ride home...now when I turn the car over...it rough idols to a sputtering stop. Any suggestions? I did put an automatic car starter in the car, a few weeks ago. Doesn't seem to be the juice...tack is indicating the right voltage and all the electronics are working fine? Any feedback would be great.

Thanks
Mike

 

Any air intake, or any other mods?

 

No...all stock. So far just an automatic car starter...lol.

 

Few things to check....

Check for any large objects in your air filter, leaves, bags, ect... believe me it gets in there.

Check for Air Leaks on and around the Plenum, air intake, and verify that all your vacumm hoses are hooked up and in good shape..

Check that your coils are plugged in, properly atached to the plug, and your plugs are in good shape.

Your saying that the Voltage shows 13V while running and it should stay at all RPM? and ~12V when off(might be slightly below if stuff is running)
If the above isn't true check your alternator.

could be a recall problem...

 

the 7ferret was absolutely on the right track. I went to the dealership today with my car...turns out it was leaves and mean TONS of leaves in my air intake...screwed with the censors within the valve...hence the stalling. All fixed and diagnostic as well as the engine tuning under warranty. All I payed for was an air filter....thanks for all your help everyone!

 

Just curious....how the hell did you get a ton of leaves in your intake?

 

from underneath the car...the dealership apparently thinks that the pull upward is pretty strong...and over time leaves were being pulled into the intake...interesting non the less...ill be sure to check my air filter and intake often...
