Yes it's keeps setting P0420 & P0430. Everytime I have a technician look at it a day a part is bad and they replace it they clear the codes and they come right back in a few miles. I'm going to smoke test the exhaust this weekend to see if I have an exhaust leak. Then if not, I don't know what else to do. I don't have a good dealership in my area and am afraid to take it to one because they will take advantage of me because they didn't do the work to start with.
