More than likely you have a faulty coolant level sensor in the reservoir(part of). On the lean codes, highest probability is that you have a split in the boot between the throttle housing(aluminum), and the plastic intake. It usually splits in the rubber, on the lowest portion, not viewable until removed. You may also have a higher than normal idle speed as another symptom. The plenum boot is serviced by replacement.
