96 GRAND WILL NOT GO THROUGH INSPECTION. WHEN THEY PUT IT ON THE MACHINE IT TELLS THEM CATALYTIC CONVERTERS "NOT READY"

1996 Mercury Marquis • 180,000 miles

Technician at my local shop thinks the catalytic converter needs to be changed. This is a new jersey state inspection if that makes a difference.
