Fixed!
OK. here is the deal. Here is what fixed my situation. I was told the stepper motor was bad. So i got the jeep cherokee one. it did not work. i then bought one off ebay NEW aftermarket fro my vehicle and gave it to them and it did not work. i was told the ecu was bad. i had it removed and sent to a Direct Auto for a rebuild. they said the idle circuit was fried and they would have to have a whole other board so they sent it back. i purchased a used computer from a junk yard and took it to land rover. i told them to install the new computer. they did and the idle did not lower. they said the stepper motor is not a LAND ROVER stepper motor and the computer can not read the position of the motor even though it can move it. i bought the land rover stepper motor and the idle is now fixed. wasnt that easy? the lesson for me is for electrical issues, land rover charges only $99 to give you an accurate diagnosis. Land rover uses there ever so special t4 computer which no one else has. now on to other issues like tie rod ends. thanks for everyones help.

What? SPend money on my truck? I only spend $300 per year in repairs. Hard to justify a multi million dollar PC for that.

You already admited to needing a new PC, and then all you need is about 500 bucks worth of autoenginuity software. I spent a bit more than that but I have all the enhansed software for everything domestic and asian.

ok so is it confirmed that the cherokee stepper will not work with the discovery? I bought one the other day to replace my old stepper motor that was bad.... and it does work but i still have a high idle.
