Question type: Maintenance & Repair

Check engine light and vsc keeps coming on after
clearance. Auto zone ran codes getting
PO441,PO442,PO446,PO420. THEY ALL have to do
with evaporative emission sys.  Either small leak or
vent control circuit.  Also I replaced the gas cap 5
years ago.  Can i fix this myself. Been an ongoing
problem
