Sounds like you might have some water in the system that is freezing up, depending on where in the country you are. If you have a garage, put it in and try to get it above freezing and see if the issue clears.

The P1518 is a throttle body code and the purge valve. Moisture in these along with cold temps will cause errors due to icing conditions.
