QuaterPounder, i am very interested in the probs you are having with your xr6, because mine is doing the exact same thing. I've got an AU II x6 hp but it's got a mock dev 4 kit in it.
Mocky's tell me that the computer is stuffed and that they are finding it common that the computers just need changing, just i'm having trouble convincing my local ford dearler to change mine in waranty cos of the mods and that there are no codes comming up. Please help and let me know how you have gone with yours
Hey Jase, what about the 5.0? Mine does the same, will not start without throttle when cold either. Checked and cleaned out the idle controller (thanks EDXR8), all wiring and sensor connections OK.
I'me beginning to think that a new coil, dizzy cap and rotor are required...all original with 245,000 on 'em.

QuarterPounder, The IAC (idle air controller) motor isn't operating, the fault could be with the IAC motor or the PCM. Best way to find out is try and borrow a IAC motor off another car and see if this fixes the problem, or if you are handy with a multimeter check for a frequency on the wire to the pcm (160Hz), can't remember which color , it's the one that does't have 12volts supplied.
