Hey, my EF 5 litre is running EXTREMELY rich when it's cold, exhaust smells real fuelly, and it blows a fair amount of BLACK smoke, until it's warmed up, this is DEFINATLEY fuel smoke from running rich, not blue oil smoke, but when it's warmed up it's fine, I unplugged the fuel pressure regulator and the AFM to test, and it is still doing it. Also run a bottle of injector cleaner through it, however, when it's warm, it doesnt run rich and seems to work fine. What can I check next?

change the thormostat as if it is fully open when cold the computer is telling motor it needs more fuel the motor will worm up much faster with a new on and this should fix it
