When the engine experiences a hunting idle condition where RPM repeatedly surges and drops while the vehicle is stopped, this Idle Air Control Valve delivers rapid response within milliseconds; the IAC Valve stops the cyclic variation that makes driving uncomfortable. The Idle Control Valve features a low-thermal-expansion housing that maintains gasket compression across the full temperature range, while the Idle Speed Control Valve prevents vacuum leaks that could occur when metal and plastic components expand at different rates during warm-up and cool-down cycles. Before removing the old IAC Valve, disconnect the battery negative terminal and let the engine cool; take a photo of the vacuum hose connections and component orientation for reference, then loosen the two mounting bolts and pull the Idle Air Control Valve straight out without twisting; install the replacement part with the included gasket and tighten the screws diagonally. Precise idle speed control avoids unnecessary fuel consumption, helps reduce idling fuel consumption, and enhances your driving experience; Friendly reminder: To ensure this product is suitable for your vehicle, please carefully review our product details images and descriptions before purchasing;, Manufacturer: TUDEXX
