Hi hopefully somebody can give me advice, whenever the car gets to operating temperature the temp gauge in the cluster will jump straight to 130 then fluctuates between 130 and 90. Have had the coolant flushed, thermostat replaced and the coolant sensor near the radiator replaced and still my cluster bounces back and forth. When my plug in a obd scanner it says the temperature is fine and steady, but the cluster says otherwise, any ideas?
