G`day , suggestions only .

Either too much fuel or too little air would be the first checks .

Check the airclean element , the aircleaner inlet and also none metalic pipe work , pipe work can be sucked and close off the air . While doing this check the vane goes freely through its cycle , inside the airflow meter .

Pull the plugs or at least a couple on each bank if one bank is black and the other clean check the resistor packs and their wireing .

If it cleans up when it`s at running temp , check the Coolant temp sensor , one in the inlet with a plug same as an injector .

Disconnect the cold start injector , if it clears up check the cold start system .

Find the vacuum line to the fuel pressure reg , remove and look for fuel , should be none and suck on the pipe whlie it is connected to the reg should be hard work .
