Whats this pipe for?

[SHOBiz]

After cleaning my intake manifold i noticed that there is a green pipe that runs from the intake back to the firewall that is broken. It runs alongside a red pipe that connects directly to the manifold. I just started the engine and its running fine. Whats the pipe for?

It's narrow and stiff yes? It's for vacuum.

Yea narrow and stiff. The car seems to run fine without it connected.

Red and green pipes? Are these "pipes" about 1/8" in daimeter? If yes, then those would be the vacuum lines from the intake manifold to the EGR servo and the servo to the EGR valve. You should be getting a CHECK ENGINE light and the 332 error code.

332 EGR did not open/respond during test or if memory code, did not open intermittantly

Wil i have to replace it or can it just be taped up?

Ahh mine broke too.. Havent found a replacement tubing yet.. But an easy fix is to take the red plastic straw that goes to cans of WD-40, or PB Blaster. Then cut a little piece off and stick it in the green tube and connect the two broken halves this way.. Fits perfectly. Maybe a little tape to wrap around it. SDPatt is right you should get a CEL, but its a SHO, so how knows..

What tha.......where is all the color vacumm lines coming from? Is this an ATX thing? shrug All of mine are black.

They are covered with a black sleeve, perhaps yours hasnt slipped off or broken yet..?

Yes, it's an ATX and Cali. emissions MTX thing.

No EGR here....... thumbs_u

To repair the broken, plastic vacuum tubing to the EGR valve or the intake, just buy a bit of 1/8" ID rubber tubing and slip the two ends of the broken tube inside a 1" long piece of rubber tubing. Been there. Done that. (But not on my non-EGR car).
