Chevrolet Venture Radiator Problem

Just bought van with knowledge of the thermostat needing replaced... bought from the 2nd owner since 80,000 miles... now has 253700... my issues are is that i replaced thermostat drove fine with barely hot heat for about 300 miles... now temp gauge jumps hot to cold, also have had it flushed and a new coolant sensor..drove fine for 50-60 miles and now temp gauge is either extremly high or really low...mild warm heat,,, drives awesome still... getting frustrated...
