I have 2003 is300. the light "check" is on and "trk off" is blincking. Testing showed P0430 code. As I live in Turkmenistan it's problem to find the new suitible cat for my car. Are there any other ways to fix it?

no, the code does not mean that at all. it is a efficiency code for the cat. you most likely need a cat for bank 2 which is the front bank. get a real shop to confirm it for you. Roy
