Just a SWAG, but is the idle stepper motor bad? I'm making up numbers here but if the idle motor is looking for say 1 volt to open 20%, 2 volts to open 40% or whatever and yours is actually opening up 30% with 1V and 50% with 2V, that overshoot seems to fit what you are describing. Does FAST have a bench test to measure voltage demand from the ECU versus actual idle motor opening?
