Is the high idle speed of the car related to the air filter? Ask a professional to explain. Thank you!

High idle speed means AG gas volume. It should have nothing to do with the air filter. High idle speed is generally where there is air leakage. Check. Two steps. 1 Block the door of solar terms with your palm. There will be two situations. 1( 1) Engine flameout. (2) The engine does not stall. If the engine is turned off, the air leakage is inside the throttle. If the engine is not turned off, the air leakage outside the air intake system needs further inspection. Now let's talk about the problem of throttle leakage in detail. Block the idle side exhaust hole on the throttle with your finger, which means that it is a control problem of the idle motor system. If it is not closed, it means that there is a gap in the throttle. The throttle valve replica has a gap that can be sealed as glue. (How to make a rubber seal? If there is a problem with the control system of the idle motor, you can use the fuel-saving semi-automatic idle motor to solve the problem.
