Get the engine up to operating temperature. Next to the battery open the cover for the diagnostic box. Place a jumper wire between the #10 terminal and the ground terminal. Connect a tachometer to the IG(-) terminal. Start the engine and if the idle is out of spec turn the idle air adjust screw on the throttle body to set the proper idle speed.
