Asked by for the 2002 Hyundai Accent
Why did you disconnect the Idle control sensor? Do you mean the idle air control valve? Was there an rpm issue to start with? Do you possibly mean the Throttle Position Sensor? Do you have a Check Engine Light on and and did you ever retrieve the original codes?
