did you check the drift pin in the accelerator pump pivot to be sure it didn't "drift" out? Manually actuate the pump?

The idle circuit and the accelerator pump circuit are not related. If the accelerator pump is bad, it should only affect acceleration, the car will feel like it fell on its face when you hit the gas pedal. More likely you picked up a little debris in the filter, in a jet, or in the needle/seat area.
