Code 34 EGR voltage above closed limit - Failed sensor, carbon between EGR pintle valve and seat holding the valve off its seat. Remove the EGR valve and clean it with carbon remover. Prior to re-installing see if you can blow air through the EGR valve by mouth. If you can, replace the EGR valve ($85-$95).

The computer controls the idle speed by using the IAB. The IAB costs about $40. Make sure that the EGR is working properly and that you don't have any vacuum leaks before you replace it. Usually cleaning it and the throttle body with throttle body cleaner is all that is needed.
