What can cause your 1997 galant to idle fast then slow?
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.
