A 1998 Chevy Prism's idle speed is computer controlled. You will have to take it to a garage to get it set. However, the idle speed could be altered if, say, your spark plugs are seriously worn. Changing them may restore the original idle speed.
If this happened all at once, check the vacuum lines. A cracked or broken line will cause high or rough idle.
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.
