Hi there. You can adjust the throttle plate on the throttle body or adjust the throttle position sensor. If making the adjustments has no effect on the engine idle, then there could be a vacuum leak or the Idle Air Control valve (IAC) could be failing causing the idle to be higher than normal.

If you need further assistance with your high engine idle condition, then seek out a professional, such as one from Your Mechanic, to help you.
