86 coupe temp guage

[Wayne Reser]

I have two 87.5 Coupes with the very same problem.  The digital temp guages behave normally some of the time but will zoom off the scale and into fault-mode after only a little bit of driving.  Backing off the throttle will temporarily bring the indicator out of fault-mode and then the temp always is where it should be. 
   
  My hoses are good and I recently had cooling system work done on both cars; my mechanic in one case and me in the other (Look out! He's got a wrench!!!).  No change.
   
  I figure the odds of both water pumps going on the fritz is relatively low and I have no other pump related symptoms. 
   
  My bet is on the temp sensors, but I will double check the obvious and not so obvious stuff mentioned.
   
  Mark, email me off-line and we'll compare notes...
