Floating idle?

When I drove my car around the block I noticed I could take my foot off the gas and it felt like the idle stuck ,it would hold and keep the car at speed when I took my foot off the gas.

check for a sticky throttle. The tbi base probably wore around the throttle shaft and now it hangs open.

Along with Dimented said check for vaccum leaks. The smallest leak can keep the revs up pretty high.
