A cylinder misfire can be from numerous things.
Bad spark plug or an improperly gapped one, a damaged plug wire, an ignition system fault, a weak coil or moisture penetration to any of the above.
If the Cat converter was faulty, you would have a CEL (Check Engine Light) on with a code waiting to be read to narrow down the area of fault. The code would show as (example:P0123)
