I went to autozone to have my Service Engine Soon Light code pulled. The guy pulled the code "P0455" and said it read something about an EVAC leak large? Something like that? What could this possibly mean?! 
BTW the code means: "P0455 Leak or Blockage Detected in Evaporative Emission Control System."
Is this severe and fixable by myself?
