Hello Ken,

No, but I did see an email  which indicated a possible faulty Frequency Valve
C.  I haven't looked in the manual on what it takes to change it out or how
to locate it.  I thought maybe I could get some insight before giving it  a
try.  I would expect someone already has performed this and probably would
have some words of wisdom which would probably save me tons of time if I
pursue it .

Let me know if you come across any information. Sometimes it idles back down
ok but most of the time
in the colder months it always remains to high. I usualy end up turning the
AC on to get it down so I don't mess up the trans.
