just got the Mrs a 2.0 Focus, 2002. All seemed fine on the test drive, but on the way home the idle started buggering about. Grrrrr

After a bit of research it seems to be a fairly common problem, which I'm glad about! Looks like it messing about when getting warm, going from normal idle to just under 2000 rpm, to stalling at times.

I'm going to investigate further, and replace the ISCV and PCV if needed, but....

There's a curly pipe coming from the bulkhead to what I'm guessing is the fuel rail with push connectors, now I would have thought (rightly or wrongly) that this is the fuel in, but it seems to be a very loose fit and sounds like it's pissing air out..... Is this the fuel rail, and if so, is the noise fuel under pressure?

Didn't take a pic, and can't bloody find one! Hope someone can help.

Edit: Maybe i should've posted this in the technical help section? Mods, please feel free to move if needed. Sorry!
