There are two vacume hoses coming off the back of the intake manifold on the 2.3L. One of the hoses is about a half inch in diameter. Today it slipped off and my truck idled crazy rough. It showed trouble codes p0135, p0136, and p0141 all indicating 02 sensors. However, I discovered the fact that the hose came off and reattached it. Problem solved sort of. The hose itself is soft and should be replaced!! Where does the dang thing originate and what does it do or what is it called? I need the infor to order the part and replace it!
Thanks in advance for anyones help!!!!

98% of hosts underhood, vacuum and cooling system, are replaced with generic hose, sold by the foot, from auto parts stores. Some metal/rubber combination hoses are OEM available only.
Get a length of hose from NAPA, etc, and cut it to length. Install.
If you have some concern, post a picture of the underhood area in question, but don't make it a closeup that loses all landmarks, or post several.

A hose that size sounds like the line to the brake booster.
