No,  sorry, I can't.  On the  contrary, I can  only enlarge your list of
possible causes: another  possible culprit might be  the Air Flow Meter.
First,  there's another temperature  sensor in there.  Electrically this
one    is the  same   as the   Temp   II sensor,   so   if  you  get the
temperature/Ohms diagram from a Bentley manual  (or maybe from somewhere
on the Web, I don't know whether it's included in the Haynes manual) you
can check   both this  sensors using  an  Ohm-meter.   Second there's  a
variable resistor in there which is mechanically driven by a flap in the
intake air stream.  Impeded mechanics in the Air Flow Meter depending on
ambient  engine   temperature,  or  even  simple,  temperature dependent
leakage  between Air Flow Meter  and  engine may  cause  a wide range of
symptoms.

Sorry for not being able to offer more specific help.

Sincerely
 Rainer
