As far as I'm aware of - there are NO parts stores that employ qualified personnel to perform automobile diagnostics!

They have a handy little code reader and that's it .. They also love to sell parts - whether you need them or not..

Good luck with the repair!

If this is my car, I clear the codes and road test to see what comes back and when. And, obtain the assistance from a professional technician who can help troubleshoot your concern.

From the surface, it seems like you have something going on with the fuel / air mixture ratios and the inputs that control that, as a result possibly catalyst inefficiencies, and a separate issue with your transmission.
