there is a bleed screw under the intake manifold... not sure if this could cause the problems you are experiancing?? has she been mapped or roughly set up since the rebuild??

hunting is usually caused by an air leak in the intake system. Would explain a low manifold \'pressure\' (Which is actually vacuum on idle!)
