Hi guys,

My turbo has just started running rough. There's a whistling sound under throttle. Popped the hood and there looks to me something missing from the throttle body. If I place my finger over the whole she runs perfect. What is missing?

Indeed, it is the idle adjustment screw.

Is the screw missing completely? If not, then there will likely be an o-ring that needs replacing.

Then you will have to reset your idle again.

From the photo it looks to be completely missing.

On the Turbos you are meant to set the idle in a particular manner although Clark's Garage does describe the procedure.

Cheers guys! I've bunged it for now so at least it's drivable.

It's the gurb screw it sets the idil speed. I got mine right then drop a drip of lock tight on it. May have used super glue

Unless someone on here has a throttle body they are not using, your best bet is probably your nearest OPC. The item appears to be listed in the PET as 951 110 919 00 - Throttle screw (best to confirm with them though.. :wink: ). It is item 15 on illustration 107-15.

Hope that helps..
