normally when u turn on the key, you should hear the cit..cit sound from your throttle body area.
ISC is located at the throttle body.u can replace it by changing the whole set of throttle body or juz the ISC gear. it will cost you somewhere not more than rm300.or u can by pass it by using FICD from superchager engine.i got one unit of FICD to let go if u want it.
