I have a 2002 Dakota, 4.7 v8. I have a error code, (Auto Zone said it's P0422) stating there is a slight vacuum leak in the fuel system somewhere. I've replaced gas cap & a hose underneath the truck at some box where the hose was cracked. The error code still comes back. Has anyone had this problem? What could it be?
