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...
