  3. Start engine and allow it to reach normal operating temperature. Connect a fused jumper wire between terminals No. 2 and 4 of test connector, located next to battery. See Figure . Connect a voltmeter between terminals No. 6 and 4. Idle speed and IAC duty should be within specification. See IDLE SPEED SPECIFICATIONS  and IAC DUTY AT SPECIFIED IDLE SPEED  tables.
  4. If idle speed and/or IAC duty requires adjustment, turn idle speed adjusting screw to obtain correct idle speed. See Fig 1 .
  5. On vehicles equipped with A/C, turn A/C switch to ON position. With A/C operating correctly, verify idle is 950-1050 RPM. If idle speed is not within specification, check A/C ON signal circuit. After adjustments, remove service wire and reinstall protective cap on throttle body. Recheck idle speed.
