1. Check for vacuum leaks
2. Check to make sure the cold idle screw is not set really high(That's a cause of unknown high idles and why people can't get the car to idle down."
3. TPS sensor could be going out but if already replaced... You need to do a base idle reset.
4. If you are using low grade, cheap gas like 87 or 89 octane, you need to step it up and use the 91 or 93 like the car suggests. I made the same mistake and not my car runs great.
5. Check for positive battery connection. My battery cable is going extremely crappy and when your volts dont run where it should be, the computer runs an rpm increase to prevent your car from dying and all other problems arise then.

Why does your 1998 arctic cat zl500 idle high?
There are a couple possible reasons. It could be a cracked carb boot that is letting unmetered air into the engine causing a lean condition. It also could be a cracked crank seal causing this problem. Check your plugs to see if it is running lean. Spray carb cleaner onto the carb boots when it is running to see if theres an idle change.
