The catalytic converter was ruined by the misfiring. Your new one will be too. Compression test cylinders two and four since you replaced the fuel injectors, ignition coils, and spark plugs. If your engine uses spark plug wires, they should be replaced as well. You can also move the misfiring coils to the firing cylinders and see if the misfiring follows the coils. In other words put coils 2 and 4 on cylinders 1 and 3. If 1 and 3 start misfiring the coils are bad. Hope that helps! Jim
