P0430 is for your front pre-cat, not the main cat.

See this thread for some info:

As for the 505 code, see if you can download an FSM for more details on that.

thanks, a little intake leak right after the MAF or IAT (intake air temp) sensor caused it. i think its the IAT anyway though IAC would solve that, but nope. fixed. thanks guys
