When it starts up 1st thing it is fine. Idles at 900 rpm. It's just when it warms up when all this happends. Its not the ICV as we have tried it with another, it idles fine when we disconect the AFM but it means its over fueling. could ut be the lambda? everyone we've spoke to says air leak would tha also explain the revs going up and down in the vid? Thanks.

Yeap, air or vacuum leak can cause that, alltho... If its fine when its cold you might wanna check the temp plug.. they are very prone to erotion, you might wanna brush it off aswell... just incase.

Also to answer about the lambda... yes it could, when i connect the lambda on mine it choaks itself on fuel when i press down the gas, so definately worth looking into :)

Intresting... Try disconnect the airflow meter, if that does nothing, try disconnecting the lambda... if none of those do anything I would search for a vakuum leak. (dosnt really appear to be the Idle control valve... but its also worth looking into)
