SOURCE: check engine light
this is very common on these. the upper intake seals leak and should be replaced. It is not a noticable vacuum leak and is usually worse when the engine is cold. It is not a very difficult job to do

It means that your MAF Sensor is dirty or faulty, or you may have a vacuum leak downstream of the MAF Sensor in one of the hoses.
In most cases, just cleaning the sensor will fix it. Otherwise you'll have to have all your hoses inspected and or replaced and also a Dirty Fuel filter can cause this code

oxygen sensors are telling you that the mixture is too poor on ur sistem need to check its behaviour and see whats causing that lean mixture
hoope this helps

Those codes are for the oxygen sensors, lean fuel mixture on both banks. Change them, problem with stalling and rough idle should go away.

System Too Lean (Bank 2)
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.
Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.
