So if you know what the problem is, what's the question?

 

well we dont know how to fix it...haha

 

ICU stands for "integraded control unit". That is a part that plugs into the back of your under-dash fuse box.

The IACV (idle air control valve) is probably what he's talking about. I'm guessing his problem is either leaking/incorrectly installed vaccum hoses, leaking throttlebody or sensor gaskets, or broken/damaged wiring. Usually broken/damaged wiring is accompanied by a check engine light...

Also, did he try adjusting the idle set screw? There is a procedure outlined in the any manual for that vehicle.
