I change the spark plugs , ignition coils and wires and still throwing the P0300 code random misfires . Also it's saying that both Catylic converters are bad . What should I check next for the random misfires Autozone is saying that it maybe my Fuel injector pressure regulator can't locate it on...- Alphonso Jackson
