Is it too high? If yes, is it becasue of vacuum leaking? I have done TB cleaning two weeks ago.

A vacuum leak is the most common cause. When the engine is still cold, use a spray bottle to squirt water on the intake manifold gasket and vacuum hoses. Watch for water getting sucked in or a change in engine speed.
