There are a few things that could be going wrong. I would start eliminating things that are due for service anyway and on the cheaper end of the repair scale.
Start by replacing the thermostat and flush and fill the anti-freeze using a 50/50 mixture of anti-freeze to water.
The nezt thing I would look at if that does not solve the problem would be the temperature sensor.
Depending on the motor in your car, if it is a 4 cylinder I think it will be either a D-series or B-Series, the sensor for the temperature gauge is actually the temperature of the engine oil and there is a seperate sensor for the car Computer to take readings from to make adjustments.
If you have any further issue, let me know and we will go through that nexr step.
