The remaining auction will not go well. The Fed today basically takes one step back, choose a wait-n-see stance. In other words, they have no clue, and stops pretending that they have one.
The Fed can print fake money to either save the US debt auction, or save the stock market from collapsing, but it is difficult to do both. And once the Fed stops printing money at frenzy speed, as indicated by today's statement, both will fail.
