I am having issues with my vacuum hoses on my 90 4.2L YJ. There seems to be hoses that have dry rotted and dangling loose under the hood. I've slowly started to replace the known good hoses but now at a loss of where the other hoses go. Thing is; my jeep will start but slowly die, starts misfiring and eventually dies. When I gie it gas it's sucking, like litterally sounds like its sucking in or not getting enough air or something. Seems like the vacuum advance is not connected somewhere.

Anyone know of a good diagram or some way I can just bypass all this, I heard of the nutter bypass, will this alleviate my issues? Please help, I need to get my jeep back up and running since my other vehicle is down and I can't ride my motorcycle. Thanks in advance!
