Almost certainly you have a leak, and it's probably pretty big. I would suspect the big plastic pipe between the air mass meter and the throttle body. Many times they get holes in them where they rub on the strut tower. You don't usually see them unless you remove the pipe - look real close and while bending the pipe around as many times the holes are hidden inside the pleated things. The next thing I would look for is a leaking intake manifold gasket, there was a thread on this earlier this week about techniques to find this.
