Question about 2000 Mazda MX-5 Miata
The cat converter was trying to burn all of the excess fuel that was being sent out of the exhaust due to the misfire, got way to hot and melted the inside of the cat. I experimented with this while in tech school. You can burn up a cat in about 15 minutes at around 3000 rpm with a single cylinder misfire. I also work at a shop that specializes in miatas, and have seen this before. Get a new catalytic converter.

IF YOU HAD MISFIRE PROBLEMS,IT PROBABLY DAMAGED CATALYTIC CONVERTER BY TOO MUCH UNBURNT FUEL ENTERING CONVERTER FROM THE MISFIRE CONDITION..IF YOUR SURE MISFIRE CONDITION IS CORRECTED,THEN YOU MUST REPLACE CONVERTER
