Is there a sealing ring inside the throttle?

Without the sealing ring, the car idles at high speed and consumes oil. If the sealing ring is sucked into the intake manifold without being taken out, it may affect the engine. It is recommended to go to the repair shop to remove the intake manifold and take out the sealing ring to prevent future troubles. If it is taken out, the idle speed of the engine is stable and normal, which proves that there is no air leakage. If there is no air leakage, it will not affect the power of the other party, but it is best to install a sealing ring.
