Found yet another problem with my sti !!!!!!!
 

I noticed a hissing coming from the engine bay after I parked up earlier popped the bonnet and it was coming from the idle control valve I removed it to find there was a split in the gasket allowing coolant to mix with the air intake I'm hoping that this was the cause of my rough running when under boost does anyone know where I can source a replacement gasket I'm having trouble finding one ?

Easiest thing to do is remove the pre heat .
Disconnect both the tubes going into the throttle body and then remove the easiest one the push the open end you have onto where you removed the other tube if that makes sense .

So just disconnect the feed and return coolant hoses from the throttle body and join them together to bypass the throttle body ?

Yep as long as the air bits sealed job done :)

Nice easy mod, thats what we like........
