My Jeep was idling erratically a few months ago and it turned out to be the TPS. It was a 5 minute fix. Might be worth lookin' at.....

Could be the TPS (throttle position sensor) as mentioned by Trailerking. Or, probably more likely, a vacuum leak since you say it also whistles. Has there been any work done to the engine where a vacuum hose could have been left disconnected or damaged, or has the exhaust manifold ever been replaced or has the intake manifold ever been removed or worked on? 99% of the time, a high idle can be attributed to a vacuum leak and any of those last three items I mentioned are common causes of vacuum leaks.
When you have a choice, buy American.

My YJ had similar issues a year ago. New intake manifold gasket solved it all.
