a little hint for a d40 overheating issue, nissan had issues with the coolant resovour bottle not moulded properly and over time the radiator cap on the bottle wouldnt seal properly, thus causing it to overheat. be something to check
yepp im going with either suction control valve issue or problem with the fuel rail/fuel rail sensor, very very common for this to happen here in nz, we have done heaps of them.
