I have a broken bolt on the top of my intake manifold would this cause air to seep in. It does have a gap where the bolt is broken off. Could this be the reason that my car idles to high?

If you have a speed density system, map sensor only, unmetered air can cause the idle to go high. Any applicable mil codes? You can check throttle valve-- check iac-- clean throttle-body.
