Hi there,

The code P0430 indicates that the bank 2 catalytic converter has failed. If it's broken up and plugging the exhaust system, it could cause a poor running condition. This is the first converter on the driver side of the engine, right off the exhaust manifold. The P0328 is a knock sensor code. I would repair the converter, clear the codes and see if it comes back. It could be the result of a poorly running engine.
