ford has a technical service bullitin out on this vehicle for the intake gaskets leaking causing a vacum leak that set codes 171 174. the solution is to have the intake manifold gaskets replaced . call your local ford dealer and see what thay can tell you about this bullitin.

THIS JUST HAPPENED TO MY 5.4. HAD IT PUT ON COMPUTER TO FIND OUT WHICH CYL'S WAS MISFIRING, AND REPLACED THE COIL PACKS ON THOSE CYL'S. THIS FIXED MY PROBLEM. IT WAS AN EASY FIX BUT EACH COIL PACK IS AROUND 50$, AND EACH CYL. HAS ITS OWN SO THERE IS 8 ON OUR ENGINE NOT A CHEAP FIX. NOT GOOD TO TRY TO DRIVE WHEN ENGINE LIGHT IS FLASHING WAS TOLD THIS CAN CAUSE CATASTROPHIC DAMAGE TO THE ENGINE. HOPE THIS HELPS, AND GOOD LUCK.

code P0420 & P0430 usually indicates a problem with catalitic coverter restriced/clogged
a muffler shop can run a test to check this .a misfire in engine can also be a culprit of coverter
going bad because of unburned fuel going through exhaust system
