my sisters alhambra will not idle at all under 1000rpm unless you hold foot on throttle to keep running. I have cleaned as much gunk (which was very little to be honest) out of throttle body with rag and carb cleaner etc.

oppersite the throttle cable on other side of the throttle body is a stepper motor that does anti-stall/ cold idle (i presume!).
THIS is pulsing open and shut madly! with ignition on and car running and not running (like it's lost it's setting..)

Is the stepper unit faulty or is it a controlling sensor ? IF so what sensor and where? there is no ECU or engine check light on.
