Vaccume controlled idle

Ok ive been having a few problems with my 87' 2.9l It was runing just fine until i had to take the distributor out in order to get the lower intake off. Well I got the distributor back in and everything all hokked up and the idle is crap! I pulled the distributor out and moved it back a tooth, foreward a tooth, ect... no good there. well I got it to where It would startand it was idleing good untill I hooked up the little vaccume hose on the rear drivers side of the upper intake, shaped kinda like an "S". Once that was hooked up it died, un hooked its fine. The vaccume hose was attached before so I know its supposed to be. Anyone know what could cause this? Im hopeing something as simpple as a clogged hose.

The distributor needs to be adjusted using a timing light. If you have a Haynes manual for your year truck ,it will show what the timing should be set at.
If that vac hose leads to the distributor ,that is what controls the vacuum advance which changes ignition timing.

The hose is attached to a cylinder that has two other hose's that go off into i dont know where. Ive tried to set the timing but can never find the "single lead out" wire from the distributor to disconect it so the computer allowes me to adjust timing.
