I change the spark plug wires The temperature gauge sensor and a thermostat and it still lookin like it want run hot

Some of these were programm d to idle up if th computer sensed higher than normal engine coolant temp, double check it with a live data scanner just verify that the ECT sensor is seeing the same as the engine temperature sender for the gauge. If it is actually running hot you need to find out why quickly as these engines blow headgaskets very quickly if the heat is too much.
