hose identify
The hose outlined in this picture on my car, I found broke down where it starts to come up through the intake manifold. I was curios what exactly is it for and what is it that it connects to below?

Re: hose identify
well after awhile itll throw a code that scanned saying idle air control system. could that still be air in cooling system or is it most likely a vacuum?

the hose is attached to a valve on top of the black box slomofo mentioned, the valve could be clogged, fairly easy to check and cheap to replace. if you take it off shake it and listen for clicks, if it doesn't then its bad or needs to be cleaned

Re: hose identify
Take the hose off from the manifold and cap it and see if it changes anything, you can remove the whole PCV setup and it shouldnt do anything as long as you cap it on the manifold. All it does is send blowby back into the engine and the PCV is a check valve.

I you look in the photo its the aluminium and black plastic thing bolted to the rear of th intake manifold (very top of the pic). 2 bolts, 2 hoses, 1 electrical connector to remove I believe

Re: hose identify
take intake off and plug the throttle body with your hand, does car die/sputter and almost die? if no, vacuum leak is causing surging idle. Might wanna clean up your iacv too (on back of intake mani, 2 12mm bolts) with some carb cleaner.

Re: hose identify
Spray some engine starting fluid around where you suspect a vacuum leak. Try plugging vacuum hoses coming from accessories like the brake booster to eliminate leaks as a test.
