i just bought a 1989 toyota 4x4 xcab 5 speed manual that had a 1994 toyota 4runner auto put into it... i have found vacuum lines that go nowhere and wires that connect to nothing and i was wondering does anyone have and ideas on how i can check verify all parts and make sure this thing is put together correctly ... i mean i drives ok but my gas milage went from 20 when i bought it to about 10... i don't know what is wrong... granted i am trying a few things and they may work but ... man trying to find whats correct and not is troublesome... please any input would be great

 

honestly
pics of the plugs/ lines would be very good help. if anything, since its from a 94 runner, it could have some things that werent on YOUR 89.
get where im going with that?

 

check my other thread and look at some of those pics, they may or may not help
