Check that the electric cooling fan in front of the radiator comes on when the engine is hot. The stock sensor may not engage the fan until about 230 degrees; a lower-temperature fan sensor can be installed, and turning on the A/C can command the fan earlier until then.
The owner of a 1991 Chevrolet Corvette reported the temperature rising quickly at idle and asked if that was normal. The expert advised checking whether the electric radiator fan comes on when the engine is hot. The owner later found the stock sensor does not turn the fan on until about 230 degrees, planned to install a lower-temperature sensor, and noted that turning on the A/C makes the fan run below that temperature.
