[V6-12v] Injector Hiss...

[James4ihl at aol.com]

This is just a guess, but there are two little rubber O-ring seals on each 
injector - maybe one of these has given up. They're about 12 pence each, so they 
won't break the bank if you want to try and replace them just in case! Also 
bear in mind that there's a big intake manifold gasket that runs right around 
the intake pipes behind where the injector rail is - it seals the upper>lower 
intake manifold. Just as likely you have a leak in that...

Good luck!
