Check Engine Soon light & P0430 code

A code P0430 means that your Bank 2 Catalytic Converter is weak. The only thing you can do is to replace the converter. Go to a good exhaust shop to see what they charge, I would say that it will go for $400+. Make SURE that they know which Cat it is because on your car I believe there are 2 warm-up Cats and a larger central Cat. Put it up on the rack to make sure. The Bank 2 Cat is adjacent to the bank of cylinder's WITHOUT cylinder #1.
