			Did you go back over your throttle linkage to verify that it is at idle? 
 
I had just the opposite problem when I replaced my head gasket, oil in water.  When I finished I had a low idle problem.  I found the problem by checking the DTC codes and it pointed to the Air Flow Sensor Potentiometer.  It turned out that I had inadvertently reversed the Air Flow Sensor Potentiometer plug and the Throttle Position plug.  They are identical and next to each other.   So after swapping them back to the correct components, the idle returned to normal. 
 
Good luck finding your problem.
