Post Catalyst Fuel Trim System Too Lean Bank 2
The engine is running too lean (not enough fuel) after the catalytic converter on the right side, meaning the air-to-fuel mixture is imbalanced downstream of emission controls. The engine computer is unable to correct this mixture properly even after adjusting fuel delivery. This can cause poor performance, rough idling, and potential catalytic converter damage.
