Hi there looking for a bit of help , a car im looking at buying has a problem basically when engine is runnning the 3 rd injector up (green) makes a hissing noise ? but when u press down on it goes away

As if its not pushed in right and is leaking air or something , car runs okk but what seems to be the problem here guys ?

thanks

 

sounds like one of the O ring's is leaking. Cheap easy fix, there is an O ring on the top and bottom of the injector. Get one from your local Ford dealer or parts supplier.
