Speaking as someone who just had some bizarre CHT issues in one cylinder:

CHT thermocouples are pretty resilient.  The wire to them, however, is not.
 Double check all connections, look at the routing--is it possible it's
coming into contact with something hot?--look for kinks, breaks in
insulation, chafing, and anything abnormal.  Maybe even try swapping the
probes around (remember to relabel your panel, otherwise you will be very
confused.)  Are your temp readings matched with the engine off?

I got the same advice from the LML about spark plug insulators and issues
associated with timing - I just changed both spark plugs as a precaution.
 Granted, I'm running automotive plugs and that was about a $4
solution...but at least inspect them closely.

Best of luck.

Louis
