There is a cable going to your throttle that has a adjustment on it, its cover with a rubber boot and you will have to pull the rubber back and loosen the jam nut and screw it until idle drops flic your gas pedal every once awhile while you adj. it. Its right under your seat.(CORRECTION) This adj can cause the idle to be high if not adj right. This adj is to adj play in gas pedal which should be 1/8 and if its to tight it will cause idle to be high.
