Note: My 2d vehicle is also a 1994 Acura Legend LS.  
  
  
  
 After on dash temperture gauge shows normal operating temperature and vehicle is driven  
  
 for 4 to 5 miles the coolant overflows from  
  
 the overflow tank. What is this a symptom of?

If the coolant is boiling over, it is most likely a bad radiator cap.

Hopefully the trouble is just a bad pressure cap but it may also indicate there is a headgasket problem and exhaust gases are getting into the coolant. Having a block check test done will verify that.
