on the right side of your intake, there is a vac line that runs from the back of the motor to right by the throttle body, the upper radiator hose rubs on this elbow and rubs through. get a can of carb clean when the motor is running, idling, and see if the rpm changes depending on where you spray. spray around that line or remove it and inspect it and see if there is a problem with it. this would cause your lean code but im not sure about your EGR code, could be the DPFE sensor if i had to guess
