If there is a leak there it could. Any exhaust leak before the O2 sensor/s will give you issues.

Look, Any exhaust leak before the sensors will cause the O2 sensors to not read properly. Check the doughnut gaskets at the exhaust manifolds for a leak. If it is leaking fix it then reassess the issue after. The y pipe will not fit exactly square on the exhaust manifold this is why the doughnut gasket is shaped like a doughnut but coned. The cone shape allows for the pipe to seal even thought it is not dead on with the manifolds.

Have someone hold a rag on the end of the exhaust while you search for a leak, this will make a leak more pronounced and easier to find.

None of us can say for sure what the issue is because we can not test to see, all we can do is try to point you in the right direction with the info you give us.
