Buick Idle Control Valve maintains stable breathing of the engine when there is a surprise in traffic or the terrain. Ever since 1903, Buick has pursued a relaxed and smooth ride that enables drivers to arrive without being shaken. The marque combines hush inducing QuietTuning, intelligent dashboards and clean lines styling to make daily errands a near cruise. Its Wildcat EV concept was the sign that the company will bring that carefree attitude into an electric future without throwing out character. The badge is trusted by generations of families as the cars are a combination of old school poise with technology that works. The noise over the road is kept to a minimum, steering is light, and the seats provide cushioning that transforms long interstate trips into small talk. Even entry trims are chrome-accented and have soft plastics that will make the cabin feel adult without having to inflate the price. Idle Control Valve is placed between throttle body and intake manifold, which measures small sips of air to ensure that rpm remains at a steady level during gear shifts, during parking maneuvers or a/c load spikes. In the Buick series, a small linear servo motor moves a screw that moves the pintle with a precision of milliseconds as a digital optical encoder provides the computer with a precise feedback signal of position, thus providing the computer with precise feedback on combustion cleanliness. Long life bearings and sealed electronics allow the Idle Control Valve to shake off heat and vibration and increase engine life and save fuel at every stoplight.
