If it does it at a normal running temp have your Mass Air Flow Sensor checked
Are you low on antifreeze ?
Running the engine hot repeatedly.
A/C compressor not running
Air trapped in the cooling system.
Check to see if the coolant fan is running. With the engine hot, and running, open the hood and see if the fan is turning. If it's not, then either the fan,temp sensor, relay or wiring is bad.
If it shows hot on the gauge and it is not hot, there is a gauge or sensor problem.
Thermostat sticking. Replace thermostat and gasket.
pee on the engine it will cool down
