Ok, found another vacuum hose I have no idea where it goes while chasing down vacuum leaks. Can you guys help me with this one, too. It's a really small line (like the one off of the bottom of the throttle blade housing on the manifold) with a Tee/Wye coming out of it with two short peices of 5/32" hose hooked to it.

P.S. I hope to help you guys as much as you've helped me one day

 

Ok, traced it out, the other end attaches to the canister under the driver side headlight. It's one of the tiny vacuum hoses. Where should the end in the picture hook up to? Thanks.

**edit** Found where it goes, hooked it up. no change, oh well. I'll keep looking for what's causing my 4.3 to lope. Thanks.

 

It looks pretty similar to my problem, was a small tube going to the interior. For reference:

just for clarification. That end in the picture got hooked to the back of the intake right? There are only 2 lines on the intake, that one and the booster line. The tee goes down to the trans mod valve and the far end of the split on mine goes to a 4 way tee that gives vacuum to the transfer case, cruise control, blend door actuators, and vacuum ball

 

Yeah, I got it hooked back up, but didn't make a big difference. I thought t went to the charcoal canister, though. I'll look again. Thanks for the help!
