97 Wrangler High Idle HELP!!!

I have a 97 Wrangler. The other day it started to idle high. It Idles at 2200 rpm. It is not speratic. It runs just like it should but at 2200 RPM. I think it may be a vaccum leak somewhere but I looked everywhere and couldnt find one. Another thing that is puzzeling me is that I have no check engine light on. I did some tests on the Throttle Position Sensor and ruled that out as the problem. Any suggestions would help out greatly, I am stumped on this one.

if the idle is real high you most likely have a vacuum leak on the intake manifold somewhere either a blown,rotted or disconnected hose or possibly the intake manifold gasket itself but most likely a hose
