Hi just wondering if the butterfly on the throttle body should be completely shut when removed from the car,even when I plug it in it flickers but dosent fully shut there is a slight gap bottom and top,the fault was coming up position switch but on mine it's built into the throttle body and can't be replaced separate,

 

Any one help thanks

    As far as I am aware you need to change the complete assembly as I haven't heard or read of anyone servicing them. You could try companies like Cartronix or ECU Testing (Google should help find them) both have good Reputations

    As far as I know the butterfly is closed until energised, then open enough to allow idle settings

    Good Luck
