    The serpentine belt itself should not have any causes for misfires or the parts around it.

    What could happen is if the water pump is driven by the serpentine belt and you drive for some time without the belt, then the engine can overheat and damage parts to make misfires.

    Check that the serpentine belt did not damage any spark wires, vacuum hoses or wires when it snapped!

    I have carefully inspected all connectors and wires belonging to the ignition coils the only wires that appear damaged belong to the fan sitting behind the radiator and in front of the engine.

    The engine light came on briefly and when I did obd 2 scan 5 codes came back. 4 codes disappeared when I closed the box with the air filter.

    Now no engine light is on but the car misfired badly
