Check valve (off a starion) is good and I haven't driven except around the block, but still should have had enough vac to help it stop. The booster was fine before the swap but with anything this old it could be. One problem after another, but is turning out nice. Just while trying to get it running and boosting I found a bad wire in the harness for the maf and at the same time had a coil that bench tested fine but was not(imagine that).

Eddie, What is that off of? I might have just enough room for something like that
