   I would first make sure that is the problem,
   But NO! there is no cleaning or rejuvenate a converter. there are products that CLAIM they do, but I have never heard any positive results from it.
   But there is a reason why this has cloged up,as rich fuel, burning oil etc, I would have that checked out also….

   Catalytic converters are permanent and very durable parts of the exhaust system. Everything else along the exhaust piping will wear out or fall off before the converter does. I believe something else is triggering your CHECK ENGINE light.

   I think I know whats going on here…you said its a 96 model, right? These have OBD2 systems which uses 2 or 4 oxygen sensors to monitor the efficiency of the converter(s). Example: one 02 sensor is in front of the converter, one behind the converter…both are in the exhaust stream. On a normally operating system, the sensor in front of the converter will give a certain reading. The sensor behind the converter *should* give a reading that is lower than the one up front. This tells the computer that the converter is operating as it should. Now, if the 2 sensors start giving readings that are closer to each other, this tells the computer that the converter isn’t doing as it should and trips the check engine light.

   Now that the system has been explained in a nutshell, I would first replace all the sensors (O2) in the system…this will benefit you in more ways than just turning the light off (like saving gas). IF the sensors still pop out a code for converter failure, I would first ask Ford for the emissions warranty for your vehicle…it goes WAY beyond the 3/36 bumper to bumber because it is Federally mandated. If Ford can replace it for free, let them do it.

   Most times it the Sensors. You have them before and after the catalytic converter. The one closets to the Exhaust Manifold most susceptible to heat, the ones under and after the converter susceptible to road damage. Just Shade Tree mechanic-ing I would suggest replacing the one at the exhaust manifold. I not sure if you can actually test it. Just trial and error replacing.
