Hi guys, have searched but can't seem to find much of an issue, has some boost issues so been pressure testing all my pipe work and in doing so I have found a large air leak coming from the throttle position sensor.
When I remove the TPS the air leak appears to be coming from the throttle spindle, there is a seal in place but doesn't appear to be anything holding it in place.
Anybody know if this is common and any known cures?

Cheers Ian.
