In such a situation one cannot do anything better than taking their car to a dealer service department or a muffler shop if they have no skill and appropriate equipment for this.

Nissan Altima Catalytic Converter

The Nissan Altima Catalytic Converter transforms carbon monoxide, hydrocarbons and oxides of nitrogen into carbon dioxide, water and nitrogen so that harmful gases are reduced. Located close to the engine for quick warming, the component contains a monolithic honeycomb ceramic substrate on which precious metals like platinum, palladium and rhodium are coated. The substrate has a large surface area to allow exhaust to flow over the coating while redox reactions take place on the surface. To comply with legal regulations in the United States, a vehicle needs to have a converter so a working Catalytic Converter is essential for keeping the sedan within emission standards. The design of the Catalytic Converter combines reduction and oxidation functions by first stripping nitrogen from the NOx and subsequently burning the unburned fuel to clean the CO and HC. A Catalytic Converter that is on its last leg may rattle and shake as the honeycomb inside it breaks apart. This incident may restrict the flow of the exhaust. It can also cause the code P0420 to trigger. This may lead to loss of power or misfires in your Altima. Keeping the Catalytic Converter clear of raw fuel prevents overheating. Through periodic inspection and timely replacement, the Nissan Altima keeps working cleanly, helps the Altima pass tests and keeps Nissan emissions reliable while supporting Nissan efficiency.
