Try to do a global reset on the engine computer.To do this disconnect the positive and negative cables from the battery and take just the cable ends and touch them together for about 1 minute.This discharges the computers electronics and resets it.This can sometimes correct an idle issue after modifications have been done like this here.If you try this and it does not work let me know.
