PO446 EVAP error?
Our 2007 HHR is bringing up a PO446 error/CEL, and we have already had
the EVAP Solenoid replaced and a smoke test run, and then last night, we
replaced the gas cap with an OEM one from the dealer. The light still hasn't
gone away, and when we go to fill up the gas tank, at least before we
changed the cap, it would make a suction sound when we unscrewed the
cap, and it would click the pump off every $1.50 or so when filling from a
quarter of a tank. There was also a heavier than normal gas smell coming
from the tank.
