Well i cant figure this one out... My car has no idle control.... the isc control works because when i start the car it revs to about 1800-2000 and drops back off, and when i put it in self test the revs also come up but i tried to set my idle 450-600 ISC disonnected then engine off plug it back in... it does nothing... runs like a bag of s**t... WTF... id like to have my idle speed control working for when my car is cold and when i turn the steering...

You may need to adjust the TPS sensor if you changed the idle screw.
