Surprise during ICV cleaning of my 318i (m42)

[mauricio88]

Anyways,, im currently cleaning out my ivc because im trying to fix a bouncing idle and i find that 2 of the tubes were f&*%ed up. The double ended one that connects to the IVC had a 1.5 inch crack from the ivc! So i continue and i see that this little tube that i have never seen is broken completely in half! I was wondering if anyone could tell me if these problems are probably the reason my idle shuts my car off when i put it in neutral.I was also wondering the price range of these parts and what the little tube does.. Ive included pictures to show you which ones i mean.
Help would be greatly appreciated.

that would affect ur idle 100%

The smaller line is the fuel pressure regulator line. If disconnected, the fuel pressure to the rail should raise about 5-7psi. If the bigger pipe that connects to the injector vacuum lines and the ICV is messed up, that would definately mess things up as far as idle and drivability goes.

heh, YEAH!
i don't know what the tubes are called but if you find out, go to pelicanparts.com they will most likely have them available.
