Idle Air Control Valve Compatible with Nissan for D21 for Pickup 1990-1994 Idle Air Control Valve IAC Valve Auto Replacement Parts 237810F300
TUDEXX
When the engine experiences a high idle condition that slowly returns to normal after throttle release, this indicates the idle air control component may be responding slowly; this component restores proper dashpot function, eliminating the delayed return to base idle speed after the accelerator pedal is released. The precision-ground valve seat and plunger tip geometry are matched to create a metal-to-metal line contact seal when fully closed; this design keeps leakage within a very small range while still allowing fine air metering through the gap between tapered surfaces at small openings. After removing the old unit, use a clean cloth to temporarily cover the open intake port to prevent debris from falling into the intake manifold; remove the cover just before installing the replacement part, ensuring no fibers remain on the sealing surface. 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
