Never had a problem with the Berks and codes before that...either before or after tuning.

I really do not want to spend the money on new HFCs to troubleshoot this problem. I think this may be an O2 sensor issue. I say this because the permanent P0420 went away after a day. Codes P0430 and P0420 came up last weekend. So supposedly both HFCs are operating below the threshold, but once again, the codes went away after a day.
I assume if the HFCs were going bad the codes would always be there.
