Would a bad catalytic converter cause misfire on cylinder 2

Misfiring on cylinder 2 may be caused by a defective catalytic converter, though this is rarely the source of misfires.

Misfire on cylinder 2 can be caused by various issues, including worn spark plugs, ignition coils, fuel injectors or even a vacuum leak. All these problems can lead to incomplete combustion in cylinder 2 and therefore trigger a misfire code on your engine.

Clogged catalytic converters can restrict the flow of exhaust gases, leading to engine performance loss and possibly initiating misfire codes on individual cylinders. Although, this may not always be a cause for misfiring on particular cylinders.

As it is highly advised that professional services be enlisted to identify the source of misfire issues, it is wise to have your vehicle assessed by a mechanic to ensure proper repairs can be implemented.
