Symptoms may include:
Causes: A code P0304 may mean that one or more of the following has happened:
P0430 Code - Catalyst System Efficiency Below Threshold (Bank 2)
Basically this means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.
You will likely not notice any drivability problems, although there may be symptoms such as a rough/hard idle when cold.
Causes: 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
- First, inspect for exhaust leaks.
- Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen O2 sensor while you're at it.
One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.
Hope helps (remember rated and comment this).

You most likely need a crank sensor thats the misfires the p0430 is caused by faulty 02 sensors change the sensors and clear the codes it will come back on a few more times just keep resetting it after 3 or 4 times it will not come back if you go to a mechanic they will sell you a cat for 400-600 bucks dont do it it is set to come on with other codes there is no sensor that tells you the cat is bad
