It sounds like the cold start injector is dirty along with faults in the fuel system; worn out fuel pump, clogged fuel filter, dirty or defective injectors, and this can expel raw gasoline and cause misfires. leading to damage to the catalytic converter. Have the fuel system tested and repaired. all this can be avoided by preforming regular maintenance on any car.
