On 2.6L, connect tachometer to White 1-pin test connector in left front corner of engine compartment. On 3.0L, connect tachometer to test connector at ignition coil (White wire).
  2. On all models, if idle speed is not within specification, rotate idle air adjusting screw on throttle body. See IDLE SPEED SPECIFICATIONS  table. Disconnect jumper wire.
