You can manually adjust the idle speed by increasing or decreasing the tention of the throttle cable.
If you follow the cable back towards the bulk head on the driver's side you will see a small plastic sleeve. The sleeve opens up to reveal an adjuster. Turning it one way tightens the cable and turning it the other way loosens it.
Ideally you should adjust it so that once the accelerator is fully depressed the throttle body is fully open. If the cable is too tight the revs and subsequently the idle speed will be high. If it is too loose the throttle won't open fully when you press the accelerator to the floor.
Remember, you should only make small turns when moving the adjuster as it only takes a few turns to completely tighten or loosen the cable.
