Clutch pedal switch? (If applicable), it is only when you go to select gear?

Oh right, it has to be some sensor on the box then, I don't know much about Auto's, but something relating to it must be telling your idle valve to open.

I had same problem on manual fez of similar vintage. Bit of a bodge but try unplugging road speed sensor maybe?
