Fast Idle & Idle-Up Control Device (Justy PFI)

Using a hand vacuum pump, check to see if control device will hold vacuum. On models equipped with A/C, ensure idle speed increases when A/C is turned on. On models without A/C, idle speed should increase when headlights, rear defogger or heater blower is turned on. See Fig 1 .
