1989 2.3 Vacuum problem
 

Anyone have or know where I can find a vacuum diagram for the 2.3 I have purchased several books but nothing in them for the small vacuum hoses. When I accelerate the inside Air fan slows down to where it's hardly blowing. I found one loose hose on the passenger side near the firewall and blocked it off. That helped but I would like to know where it should really go.
