My missing link isn't doing much so i am going to try the check valve setup, but I am unsure how to actually connect the valves to the intake manifold. The MAP sensor has a perfect place to hook up a hose but the intake manifold has nothing.
it is on a 94 integra LS
tried to do a search but didnt find anything

 

Get some vac hose and some tees, and hook up your check valves so they look like this(horizontal lines are vac hose, vertical lines are check valves, tees are at the intersections):

Then, plug one end of your completed assembly into the bottom of your MAP sensor, then put a 90 degree elbow on the other side and jam it into the hole on top of the throttle body where the Map sensor used to sit. You may have yo use some silicone or something to keep it in place, since they like to pop off under boost.

 

Use a brake check valve and you won't have a problem.

Much easier and cleaner to use a brake check valve.

You'll see pics Jeff when I send my info for your site.

 

like a speedbleeder?
