G37 mechanical issue

Postby Stone75 » Tue Oct 30, 2018 6:34 pm

Hi guys,
I own a 2009 Infiniti g37x sedan and around six months ago I had an issue where the car wouldn’t go over 2500 rpms and if you don’t pull over right away would knock and start to stall. You shut it off and restart it and it would be fine. Well I moved to Minnesota 6 months ago and it stopped happening out there. I moved back to NH yesterday and it started happening again. Does anyone have any recommendations other than telling me to scrap it lol?

Yes the service engine soon light did come on, the maf sensor code has popped whenever this happens which I’ve replaced. However it still continues to happen periodically.

Check for loose vacuum lines and or cracked intake boot near the sensor
