Check the thermostat and radiator. Do you have coolant losses issues?

When temperature reads higher than normal, how much higher than normal?
Does the fans comes on and stops when the problem occurs? If yes, it could be the sending unit, ground circuit or gauge.

That would indicate a wiring issue rather than actual overheating. Check the ground circuit connections, behind the headlights and sending unit.

Just to add to this so it will overheat while sitting in the drive thru if you dont take it out of gear and do what you say you do to keep it from overheating?If so I have had a couple of cars like that.

Please answer the questions I ask so I can help you. Does the car only overheat in the drive thru and to make it stop overheating you have to take it out of gear and rev the engine up?

At center of dash and above left kick panel there are 2 more grounding points. Check those. If it fails to solve the problem, the meter cluster is the likely suspect.

Also you can use a infared temp gun to compare actual temp with a scan tool that reads live data.
