OR ECU (sensors)

And that when i plus in and out the IACV even now its making the idle rev to another 1000-2000rpm that is must be something there.

Sorry maybe im just thinking to myself but correct me if what im saying is wrong?
You mean after the IACV?

Maybe the IACV is working to some degree but not seating, i.e can work a bit but for some reason sticks and can't close off when it's told to? If this is the case it's a bit strange though that the ECU wouldn't detect the high idle and tell the IACV to remain closed (or as closed as it can be considering it may be sticking open), thus causing no change when the IACV is connected?

Perhaps the IACV is 'stuck' wide open when no power is getting to it, but when it gets power it can close, just not all the way? If so a bit odd as I would have expected the IACV to be closed with no power...
