Help. Me please

I have a 04 tj stock except for a 2in bb. Yesterday I ran into a problem. My engine we already warmed up. And as I was driving the temp. Gauge did move like usual. But As soon As I released the gas pedal and put it in neutral the temp. Gauge climbs all the was up to the red part of the gauge. And the check gauges light come on. And the weird thing is the engine compartment wasn't smoking what so ever I was wondering what could it be and also what could I check to resolve the problem

Find out what the code is that tripped the engine light. Then start looking at the cooling system....coolant level, radiator leaks, seized thermostat, waterpump weeping/leaking, hoses, etc.

I think it was the check gauges light not the check engine light.

The check gauges light comes on any time your temperature or charging gauges are reading outside their normal range. Due to your temp gauge going into the red you more than likely have a cooling system issue, check the normal things:
Full of Coolant? Radiator and overflow tank. Don't forget to check the coolant condition.
Any Leaks? Hoses, Radiator, Radiator Cap, Gaskets on engine, Heater Core.
Air Flow thru radiator? With the engine idling hold your hand/shop rag/sheet of paper on the outside of the grille, airflow should be noticeable.
Clutch Fan operation? With the engine warmed up and Not Running spin the fan if it freewheels the clutch fan is shot.
Thermostat operation? Full of coolant radiator cap on start the engine and allow it to warm up upper radiator hose should be very warm.
That will get you started.
