Please can some one tell me where this is located under the bonnet. my engine splutters and has eratic revs and the diagnosis is that the valve it needs a bit of a clean.

i have searched the net all over to see if i can tell where it is located and all i get is that it is by the air intake.

I am not a mechanic and really dont know parts of gthe engine i just need to know where it is or where i can get pictures of its location

please help..
