Re: 86 Coupe temp gauge freaks out....

     If Phil's suggestion doesn't solve your problem, a secondary cause 
     might be a sticky (or the wrong) thermostat. I had an 87 coupe that 
     would exhibit similar problems intermittently. The PO had the wrong 
     thermostat installed and it would open at too high a temperature. When 
     accelerating, the gauge would rise to flashing level, but would then 
     come back down if I got off the accelerator. The problem never occured 
     at idle.
