what is this?
what is it? the car idles at like 2k then after sittin for a sec or so it will slowly idle down to normal idle??
car has.. trex cam, headers, ory, slp loudmouth, lid, air/egr deleted, air pump deleted, FAST intake (78mm)
any ideas why its idling so high and what is this part?
(not my motor just used it as example)
