I have replaced Bank 1 sensor 1 on the exhaust manifold. Still reading a code of P1035.

I understand that it could be a cat conv issue or a fuel mixture, but can anyone recommend how to isolate another issue for confirmation? Thanks...

did you clear the code correctly? on this vehicle you can not just disconnect the battery, you need a scan tool to clear the code
