Hey guys need help.

[Stampy]

Hey guys, not sure where to post but I need some advice on D40 2014 Navara that keeps stalling at traffic light. 

So far I've changed air filter, fuel filter, fuel rail and suction control valve but it's still stalling.

Any advice would be most appreciated

Have you checked the condition of your fuel lines? If a fuel line develops a leak, air will get sucked into the system through the crack, pinhole, or loose connection. That air is a common reason for stalling. If you have a way to check fuel pressure at the input side of the injector pump, check that too.
