Thanks, I called the zone, they are blaming it on a faulty gas cap, of course.....should be OBD II
IIRC all OBD II codes are the same
P0456 is usually a small leak, where the system can draw a vacuum, but not sustain it. Like the cap is not tight.
Those codes say the same thing that the 'zone did. I will try a different gas cap, look for possible leaks etc. And continue to ignore it.
