ive heard the cold start valve gets its reading from the etc so if it reads from this and that is wrong then itd be on all the time.

I want to unplug them all i dont like all these idiot proof sensors, i take it the blue and the and the brown plugs are the two plugs round the back of the manifold in the middel then in which case i can just disconect both?

where its al grubby round there i cant see what color they are hense why i am asking if i can just discoinect both?

not sure that there is a leak my car is just realy bad on petrol and i only use on sunny days so might aswell disonect it as i dont need it and its just another thing that may be wasting petrol.
