So i have had a very strong fuel odor since i installed my full force injectors. I also replaced the injector cups at the same time. It smokes white on a cold startup, and eventually clears up after 5-10 minutes of idling. However it always has a very strong smell of unburnt fuel. No loss of coolant or oil. When idling i checked the temps of each cylinder and they all seemed to be within 10 degrees of each other. When i run a contribution test it always shows #8 weak (cam sensor?) I swapped 5&8 injectors, no change. Any diagnostic help is much appreciated!
