I suspect the injector is not flowing properly. What injectors are you running? The spark plug is not fouled if the exhaust port is white. I would swap in one of the other injectors to see if it changes, but you would need to pull the plug to check it once the exhaust is back together. Or you could check the temperature difference between exhaust pipes for each cylinder with an infrared thermometer. You really need to get that sparkplug out. It is probably stuck from being overheated. Perhaps penetrating fluid would help after sitting awhile.
