Evap Emissions Leak


This can be because the Gas cap is not holding the pressure. I would start there first.

Code PO442 & PO455 on a 2003 Dodge Caravan with 3.3 engine


The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.
