[DML] Re: Idle speed too high - other causes?

["dmcchaser" <dmcchaser@xxxxxxxx>]

Well, the high idle is fixed...  I took the throttle plates out and
flipped them over so the relief valves would be facing the right way,
now my idle is right where it should be.
  I don't know how the plates could have been swapped around, the
split screws that hold the plates on looked original.  Could this have
been a factory error?  I can't think of any reason for the plates to
be removed from the throttle body, it just dosen't make sense.
