PO170 & PO173 error codes. Have Installed K & N Air Filter, Auto Zone ran diagnostics on it and said it was not the Mass Air Flow sensor. Ran High Grade 16-OZ SF-16 SeaFoam motor treatment. That got it to stop for 2 days but the warning light came back on again. The next step will be to remove and clean the oxygen sensors. What do you suggest?

Look for a vacuum leak and also check the air tube
