This is all due to a loose connection somewere. If your car had been worked on check all connector that are not plugged in tightly. Some newer cars even have a special lock lever to the connectors, and if not connected properly you would have all kinds of code poping up.

This error indicates too lean a fuel mixture is being delivered to Bank2 (bank of cylinders closest to the front of the car.
This could be caused by a defective IAC valve ( Idle Air Control) but more likely is bad vacuum hose or PCV valve
Check and double check then redouble check all hoses for cracks or leaks. Replace the PCV valve ( about $10)
