what's up guys, i currently have a 2009 g37x . . recently when my car is already warmed up and i start it up the car will occasionally stall out. Has anyone else ever experienced this problem ?

 

No. I've not had the problem.

 

check connections under the hood, sound like there might be a vaccum leak of some sort. you should still be under warranty. take it in and get it looked at.

 

Have you recently disconnected the battery, or power to the ECU?

My 350Z did this after installing a stereo and having the battery disconnected for some time.
It can mess up the throttle position at idle and seems to affect it after warmed up.
There are procedures out there on how to correct this...mine just went away over time.

 

does it choke before stalling? or does it straight out just turn off? does it turn over after?

 

hi

yes I had this issue which occurred suddenly just for couple of times and everything went back to normal just by itself..

but if its persistent with u, u better take it to the dealer

best regards

 

Could be that your throttle bodies are way too dirty.

I had that problem awhile back when my car was around 30k miles (they were REALLY dirty).
It would stall out right after I started up the car (warm start).
I cleaned them and reset the ECU per the DIYs posted on this forum and the problem never came back.

Check them out. Hope this helps.
I am planning to clean them again at 60k miles... which is soon =\
By the way, I have a 2008 G37S 6MT
