The po302 codes is a misfire on the second cylinder. The fuel is not burning and getting raw fuel into the cat causing damage and the flashing.
First they should swap the 2nd and third cylinder spark plug wires, then the 1st and 2nd cylinder plugs. IF the misfire moves to either the 1st or thrid cylinder you know it is one of them. If niether, iwould compression test that cylinder.
