The switch basically tells the ECU whether the throttle is fully closed, fully open or somewhere in between. So....
Either the signal ' fully closed' does not come through, the IAC solenoid is not activated by the ECU and your car would stall when coming to a stop.
WOT indication usually leads the ECU to induce a rich condition, so disfunctioning could lead to too lean a condition at full throttle, leading to loss of power/ hesitiation.
More minor: WOT indicaton should also lead to disengagement of the A/C, IIRC.
what's wrong??
