My chevy equinox keeps running hot at idle. I've had thermostat and water pump replaced. I've also had it tested for a blown Head gasket it checked out ok. Not to mention I've had the system flushed. What could the problem be. Oh yea I replaced the the temp sensor

It sounds like both or one radiator cooling fan motor is not working. Here is a guide to help walk you though the steps to replace it.

Good to hear, please use 2CarPros anytime we are here to help.

That is a very common symptom and can be caused by an inoperative electric radiator fan motor. You need plenty of air flow through the radiator to cool it. That air flow takes place naturally when the vehicle is moving. The fan is not needed when natural air flow is enough to cool the radiator. You don't usually have natural air flow when the vehicle is standing still, unless it's a windy day. That's when the electric fan gets switched on when the coolant temperature gets too hot.

There are other things that can cause an engine to only overheat at highway speeds, and there are things that can cause overheating at any time or speed. For what you described, the fan is the logical place to start looking.
