P00BBFuel Injector Insufficient Flow - Forced Limited Power
One or more injectors deliver less fuel than commanded — ECU has activated forced power reduction. A flow-deviating injector throws off cylinder balance — adjacent cylinders run leaner/richer to compensate, often masking the root cause until the trim limit is hit.
