alright, so the haynes manual ststes that it should be open, or at least partially....i've looked and taken it off the car and its open by about 3-4mm i understand that when cold it should be open and a once the car heats up, it should close? i'm confused! anyway i dont see it move whatsoever and its the type that cannot be opened, though the valve inside can be freely move open, and it springs back shut..... Having a crappy cold idle that just cannot be traced back to anything else lol
