Idling high after repairs

This weekend I replaced the valve cover gaskets on my 1998 chrysler sebring convertible JXI. It requires that I remove the upper intake manifold and the throttle body. After putting everything back together the idle is extremely high. Right now its idling around 2800 RPMs. I replaced the vacuum hose on the EGR from today thinking it might help, but its still idling too high.

Any suggestions would be helpful. I've double checked all the connections and made sure the cables to the throttle body weren't stuck.

sounds like a vacuum leak to me. check all vacuum lines, and make sure the gasket for the upper intake did not jump out while you were re installing it.

I agree, sounds like a vacuum leak of some sort, if your working on the 2.5L mistubishi engine, check your throttle cable where it connects to the back of the intake plenum on that braket. I have already installed it wrong on this engine causing the throttle to be slightly open
