A bad vacuum leak can cause both a lean condition AND a high idle if the leak is bad enough. Check over all the intake plumbing and associated hoses including the PCV hoses, oil trap box, and flame trap, etc. for cracked/disconnected hoses. Might also be wise to remove the throttle body for a good cleaning and maybe a fresh gasket where it mounts to the intake manifold.
