Driving home tonight and POOF!! P0420 now remember I got the car back 1 week ago Monday from replacing the other one for P0430........ What a PITA!! Gonna call Kachina tomorrow morning and see if I am going to have to take it in for them to read the code. I sure hope not cause its an hour there and and hour back. What really sucks is that I was going to have my emissions check done Friday.
