Little vacuum hose help?

Hi everyone ...

Had a radiator replaced in my 1997 TJ, 4-cyl a couple months back (235K miles). Since then the warm idle has been high (mostly around 2K, but sometimes around 1.5) ...

I started looking into it and thought it might be a vacuum leak ... after learning a little about those, and poking around, I found a small black hose (1/2, maybe 3/4 inch) with a white plastic tip disconnected ... coming from somewhere below and behind the engine on the drivers side ...

Could this be coming from the gas tank? Is it possibly my vacuum leak? I do get an engine light that will come on for a day or two, go away for a few days and come back for a day or two ...

Thought I'd see if it was an easy fix for me before going back to the shop ...

Any ideas?

Thanks in advance or your help and thoughts. I appreciate it.

Buy a code scanner and a repair manual.

With the engine running, see if there is vacuum present at the hose.

I'm guessing you found the axle vent hose myself. Post up a pic.

Look all around the intake manifold for vacuum hoses that may be disconnected, cracked, split etc.
