I just had the same thing happen to me. It ended up being a bad booster. btw.. I had just bought a rebuilt booster 2 weeks before from Autozone. I guess it was a defect part. They are not too expensive considering.

Also, check to see if the pedal come up some with the engine off vs on.. This will help you diagnose. and use this site.

The linkage behind the booster was rusted on mine, a little sandpaper and some neversezze di the trick for mine.
