When the engine experiences a low idle that makes the vehicle feel like it is about to shut off at stop lights, this indicates insufficient bypass air reaching the cylinders; this component increases air delivery to maintain the minimum idle speed required for accessory running, preventing the engine from dropping below the stall threshold. The return spring is made of selected spring steel wire with force treatment; after one hundred thousand cycles its spring constant change remains below five percent, ensuring the plunger returns to the preset mechanical position when control signal or power supply is lost. After cleaning the mounting flange and placing the included gasket, hand-start the two mounting screws, then tighten them in a diagonal sequence to the torque value shown on the housing. 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
