How to replace the Idle Control Valve on Buick LeSabre?

Start by removing the fuel injector sight shield and disconnect the electrical connector from the Idle Control Valve. First disconnect the Idle Control Valve electrical connector from the Throttle Body then unscrew its attaching screws to extract the valve before removing its o-ring assembly. Check the o-ring for damage before making a new purchase if damage is present. A new valve installation needs a pinch operation on the cone when it extends beyond 28 mm (1-1/8 in) or less. Place the new o-ring on the Idle Control Valve before installing it into the Throttle Body using attaching screws torqued at 3 n.m (27 lb in). Put the power on and off by letting the ignition switch cycle through each position to reset the Idle Control Valve through the powertrain control module (PCM). Wait until the engine achieves normal operating temperature then reinstall the fuel injector sight shield.
