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.

It will go up all the way if I let it but I don't I can turn the car off and right back on move a couple feet or pit in neutral and give it a little gas and it goes back down and yea the fans come on and off when it happens

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?
