Nissan Forum - Nissan Enthusiast Forums - Vq40de v6 petrol 4.0 no power, rough idle, p0300

Hi need sum help with my vq40de engine.

The truck starts right away but check engine light is blinking... rough idle and no power what so ever...

Truck seems to have no power. Idles rough... Low/deep grownling sound when i accerate. Almost sounds like its choking... exhaust smokes when i accelerate (white smoke) and smells like unburnt petrol..

Bank 1 cylinderS all fire properly but bank 2 are all dead. Bank 2 Injector tips covered with dry carbon aswell as sparkplug tips... only on bank 2 (3 out of 6 cylinders).

Fuel economy has gone terrible.

Any idea whats wrong?
