I don't have search privledge and have looked as best as I could. I did find a TSB for the P0420, but not the 430 which appears to be close to the same thing.

I do have a question regarding the possible fix of an ECU flashing. When one is flashed is it a complete download of all software in the computer, or is it just a specific piece of code? I ask because I have been reflashed once already.

Thanks,
Doug
