ZX2 Intake Vacuum Hose Broken-Whats It For?

Coming off the bottom of the plastic intake manifold, is a deteriorated rubber vacuum hose that goes up to the exhaust manifold(?). Is it for emissions & can it just be plugged off? If not, where's my best source for a new one? Thanks everyone.

Sounds like you may describing the PCV valve's elbow. Is it a 90-degree bend on a short, black plastic hose?

It may cause the car to throw codes, which will fail you for emissions (if any codes are present). It won't hurt the car other than that and possibly a bad, rough idle but it's cheap and should be replaced. Just replace the valve itself and the elbow while at it...both VERY easy and only a couple of bucks.

Wow, Thanks for the info Mr. Mcmunkee. Thats the exact hose I'm talking about. Would the hose be a dealer-only hose? I'm sure the PCV can be bought at my local auto parts store. Thanks very much.

I got mine from ford. The hose did not cost me any more than like 15 dollars.

$15? Geesh. Bought mine from an Advance Auto parts for $5 when I replaced my $2 PCV valve.

Easiest to just do them both at the same time since they're dirt cheap.

Got The New Hose Installed...

Got a new vacuum hose assembly from my local Ford dealer, had it in stock. How do I get my "Check Engine" light to go out now? Have started & stopped the car many times since the new hose install, but the lights still on? Any ideas? Thanks again everyone.

Re: Got The New Hose Installed...

It usually takes 25-40ish miles to complete a drive cycle to clear the code out, so you must have something else going on also.

Have you had it scanned? If you get the code, we can tell you what's going on. Auto Zone or Advanced will scan it for free. I prefer Autozone, they'll print out a little receipt with the code on it so you won't forget it.
