Recently, Any time I try to start my 2011 g37 after it’s been warm, it will start but immediately closes. This only happens whenever the car is warm and never happens when It’s cold. Right now I’m thinking it could be a fuel problem but I’m not entirely sure

 

Any idea when/if the throttle bodies were ever cleaned?

 

my car currently has 132k km, I probably cleaned the throttle bodies around 115k km

 

Scan the car and see if it's throwing any codes. Do you have an iphone or android, and do you have a bluetooth OBD2 dongle? If you have an android and a bluetooth adapter, you can download an app called NDSIII lite and perform an idle air relearn. If you don't have this, you can manually perform the relearn, there is a great video on youtube by Motorvate DIY that walks through how to do this. Try that, and see if that makes any difference with stalling at warm idle. Dirty throttle bodies/TB's that need a relearn are pretty common with causing stalling.

 

I do have a code which is P0106, manifold absolute pressure, I’ll give the app a try

 

A bad MAP sensor can cause engine stalling. If you have a digital multimeter you could test the sensor to see if it is within spec but it is a tricky process according to the FSM:





It would probably be easier to remove and clean the sensor, reinstall, clear the code, and see if that makes a difference. MAP sensors are usually reliable but anything can happen.
