System Too Lean at Idle Bank 2

The engine is running too lean (too little fuel, too much air) when idling on the side of the engine without cylinder #1, causing rough idle and hesitation. This is typically caused by a vacuum leak, weak fuel pump, faulty oxygen sensor, or dirty fuel injector. Poor idle quality and reduced engine performance may be noticed.
