Fast Idle Thermo Valve

$52.13 from majestic honda. (about $70 from nearest dealer)

basically, the valve is on the throttle body. it's supposed to open to suck in more air for the car on cold starts. but it's supposed to close once care reaches normal operating temperature. took of the intake air duct to the intake manifold and found out that the valve was continuously sucking in air. i covered up the hole, and the engine returned to normal idle.
