When the engine experiences a hunting idle condition where RPM repeatedly surges and drops while the vehicle is stopped, the idle air control component may be responding too slowly to load changes; this component delivers rapid response within milliseconds, stopping the cyclic variation that makes driving uncomfortable. 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. Before removing the old part, 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 unit straight out without twisting. Friendly Reminder: To ensure accurate selection, please compare the product images and specifications before ordering to confirm that the parts match your vehicle model. If you have any questions before or after placing your order, please customer service. We will provide detailed answers and assist you in finding the appropriate solution., Manufacturer: SZYNBQ
