Got a check engine light on the way home from work. Pulled the code at Pep Boys and got the P0455. Appointment at the dealership for tomorrow. Hopefully it's a simple faulty purge valve. Symptoms I'm experiencing are a slight rough idle and then a intermittent tapping sound from engine bay at idle.
