IM THINKING THAT WHEN THE INJECTORS WERE CLEANED IT WAS OVER DONE OR TO MUCH PRODUCT WITCH HARMED THE CAT..DRIVE IT UNTILL THE CAT GETS GOOD AND HOT MIGHT CLEAN OUT.. AND / OR ..This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). Catalytic converters are not normally a "wear" type item, that is they are not designed to wear out and need replacement. If they have failed, it is likely due to something else that caused it to fail. This is what a P0420 means... Leaded fuel was used where unleaded was called for (unlikely) A damaged or failed oxygen / O2 sensor Downstream oxygen sensor (HO2S) wiring damaged or connected improperly The engine coolant temperature sensor is not working properly Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe Failed or underperforming catalytic converter (likely) Retarded spark timing The oxygen sensors in front and behind the converter are reporting too similar of readings Leaking fuel injector or high fuel pressure Cylinder misfire Oil contamination
