Question about 2005 Nissan Frontier
Have had two catalytic converters go out in 2005 nissan frontier crewcab. have 116,000 miles. should this be happening?
Catalytic converters should last the life of the vehicle. usually they are damaged be a poorly running engine. most common causes are lean misfire causing unburnt fuel and air to get into the convert and ignite there. coolant or oil burning. engine running too hot (lean) overheating converters.
was it the same converter that went twice? did they change them at the same time? where the pre-converters? is the engine light on?

Tips for a great answer:
A code P0430 may mean that one or more of the following has happened:
It is most likely that an O2 sensor just prior to the catalytic converter has gone "lazy" and is not reading properly. To remove the O2 sensor, I would soak the sensor first with a rust penetrant and then you will need a 7/8" wrench or socket (depending on the sensor's location).
