You shouldn't hear any knocking or pinging from the fuel, as the engine management system will take care of that.

If the fuel was really bad, that could cause it. Not just lower octane rating, but water or other contaminants. You don't really know that it was 91, just that it said 91 on the pump. Try a different station if it continues.
