Mileage Model: Nissan Frontier V6 4wd year: 2000 How many catalytic converters does this model have, 1 or 2? What would cause me to get 9.1 miles/gallon? I'm hearing a wooshing sound on the right side of my car that sounds like air being released upon acceleration?

You have 2 cats B1 & B2 and it sounds as if the right side (B1) is clogged. If that's the case you will need to replace it with a new one from your Nissan Dealer. While your in there you should check the condition of that right exhaust manifold as they are known to crack and if so replace it while your replacing the cat. Hope this helps.

How do i fix p0430 code Nissan frontier 2005

A code P0430 may mean that one or more of the following has happened:

  • The catalytic converter is no longer functioning properly
  • An oxygen sensor is not reading (functioning) properly
  • There is an exhaust leak

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).

Have had two catalytic converters go out in last 8 months

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?

Poor fuel mileage with my 02 nissan altima

yes it very possible because the catalytic converter is part of the emissions and you need to ask yourself when was the last time you had a good tuneup drive belt,sparks and wires if needed and a fuel filter and a pvc valve.
