The cause of your 97 Galant idling fast and then slow is a high idle system, either electrical or mechanical. Basically works like this: when the car is cold, usually in the morning, the system will cause the idle to be higher than normal to help heat the engine to normal operating temperature. Once that temperature is reached it will then kick down to a slower idle. Both idle speeds are preset by the factory. This is common on all vehicles, not just the Galant.

How and where do you change the idle speed on a 1993 Mitsubishi Galant SOHC?
The idle speed is factory pre-set, and no adjustment is available. If the idle is too high, or too low, you will be having other problems that will affect the idle. In cooler temperatures, it will take the engine longer to come out of fast idle, as the engine warms up to operating temp. If the idle is too high/stays at a higher than normal idle, then take the thing to get it repaired. Running a car in gear(automatic transmission) with a higher than normal idle, can damage the transmission.
