Hi, my car is idling very high on startup. It idles so high that the exhaust manifold turns red hot. It will idle high for several minutes before it slows down, and then the redness of the manifold slowly goes away. What can be causing the high idle, and how can I check/fix the problem?

Clean out the idle air control valve and EGR valve and look for vacuum leaks
