*The positive correction value:
->The fuel injection of the cylinder
is less than that of other cylinder.
*The negative correction value:
->The fuel injection of the cylinder
is more than that of other cylinder.
*Extreme correction value identifies a
problematic injector.
After replacinga injector with new one,
reset & confirm the engine condition.

15. Replace the default injector, and then repeat previous

test modes to check if the injector is normal.
