Idle Up Valve P/N? And other stuff Options

[pandito]

Does anyone know the part number for the A/C Idle Up Valve? My 98 GT vert idles rough-er than normal when the AC is on and I think I've localized the problem to either a failing or an altogether bad A/C Idle Up Valve.

Now, previously, she would do this weird slight drop in RPM when coming to a stop so I planned to clean the throttle body as well as the IACV. Problem was that I couldn't disconnect the water lines from the TB (which is connected to the IACV) so I instead just cleaned the TB as best as I could with the air and water hoses still attached. It's idling better, but doesn't solve the rough-er idle when under AC load.

Going a little further, how do you remove the water and air hoses from the IACV / TB?

And, lastly, are there any part numbers for those specific hoses that go from the TB to the EGR-VM as well as the throttle opener? Or can I use any hose that fits those openings?

May need to twist the lines with pliers if they're seized to the nipples and won't pull free.
