Vacuume line issues

[mixedupjeeper]

I'm having trouble with my vacuume lines on my 90 xj. I made the mistake of letting somone else work on my jeep and i'm missing some vacuume lines. I can't tell where they started or ended. I just know there gone and now my jeep is running like crap. I'm just looking for ideas as to how to fix my problem. i've googled vacuume line diagrams and all i can come up with is just HVAC lines. Any insights would be appreceated.

Get a factory service manual, it will have everything you need for around $100.00, I think I may have one but wont be back home until mid january. Tim

What lines do you think you are missing? I removed most of the one's on my 89 XJ and it run's just great. The only one's that I still have on are the HVAC lines and the one vacuum line running from the fuel pressure regulator to the intake manifold, plus the MAP sensor line. If you are missing the MAP sensor line (run's from the throttle body up to the firewall, little sensor with a green harness plug) your rig is going to run like ass.

I can check mine if need be for ya to compare.....

if the map sensor doesn't fix my problem I'll have to get in touch with you if possible.
