problem with vaccum lines going from turbo to manifold need diagram or know what they are. Car is running but will bog to nothing when I accelerate at all will do maybe 35mph and no pick up. I have replaced the air intake hose and a small hose I think is actually too big for the nipple it connects to but canot find it in any diagrams to know what it is, the old one is like glue and split and gooey. can the wrong size rubber hose cause this problem and what is it called where it connects over the other side of the manifold cover to another nipple?
