Your help is appreciated.
The catalytic converter on my Mercury Mystique was failing and the check engine light was coming on within 50 miles after reset. After trying a bunch of products and fuel injection cleaners, including some snake oil made nearby in Orchard Park, NY, and that CRC Emissions FI cleaner, it seemed that having a professional intake cleaning helped tremendously.
The light still comes on, but stays off for months and over a thousand miles (don't really drive the car much as I have a truck for work). The car still throws a code for the cat being below minimum standard when the light pops on, but NY doesn't do the tailpipe emissions thingy, and I recently passed inspection after resetting the computer and driving about 40 miles...
