When the engine has accumulated over 150,000 miles , the stepper motor magnetic material in the idle control valve may experience natural demagnetization, leading to reduced output torque that cannot precisely counter the intake vacuum pull on the plunger; this component uses high coercivity magnetic material to maintain sufficient driving torque throughout the expected service life. The flow channel cross-sectional area gradually expands along the airflow direction, avoiding abrupt reductions that would cause throttling losses; this design keeps airflow through the valve body smoother at the same plunger position, resulting in lower intake noise during idle . After removing the old part, clean the mounting flange surface using a plastic scraper to remove gasket residue; avoid metal tools that could scratch the sealing surface; then place the included gasket onto the flange, align the holes, and hand-start the screws before final tightening. 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
