i posted a question a while back:
http://www.landroverforums.com/m_60659/tm.htm
i tried almost all of your advices except changing the stepper motor. i went on a long vacation and its only now that i can focus my attention on my LR.
i still maintain a very high idleing, close to 1k rpms. any lower and the engine dies when i turn the ac on. the thing is, i don''t think its the stepper motor. when i shift, particularly when im in low gear, the trk loses power. i mean i can feel and hear it starting to stall. even the ac fan slows down. i cant get my foot off the gas otherwise the engine dies. and thats not from a cold start either. will replacing the stepper motor help in this situation?
the plugs and wires are also relatively new but im sure the previous owner just put in the cheap ones. do you think its one of the possible causes of the power loss?? im planning to put in platinum plugs and magnecor wires. i read a lot of good things about em here. im sure it will greatly improve my trks performance but i wanna fix all the problems first b4 i do any modifications.
also, i remember one of the mechanics i went to said that the alternator (or it might have been the compressor he was pointing at) on my trk is only 1200(W??). he mentioned sumthin about the 96 models overheating here in the middle east so they had to replace the 1600 thats built-in to 1200s. i don''t know if there is any truth in this at all and quite frankly i barely understand it so i wanna confirm it with you guys. im still very new to all of this and generally takes the mechanic''s word for it. im doing my best to learn and i need all the help i can get. good thing you guys are there!

Don''''t know about your previous tread nor do I know anything about the D1 Gems engines, but I had a similar problem on an old Jeep of mine, and it ended up being a failing EGR valve ( vaccum related) where the ball in it would stick. I''''m sure Spike or Mike will tell if it would apply to you or not.

If a GEMS engine will not idle it is the stepper motor, all DI''s have the GEMS engine.
The lower the engine RPM the less amps the alternator puts out, so your A/C fans will slow.
I believe that LR''s have a 120 amp alternator, so I do not know what your mechanic is talking about.
And yes, replacing the plugs and wires is never a bad idea. Use the Magnacors.

Have you changed your air filter? A clogged airfilter will cause it to run rich, if it runs to rich then the fuel will not combust properly.
Re-read your first post, I suppose that if your alternator wasnt putting out like a homecoming queen and the A/C was on that your spark could be weak and then the trk could stall. But I would check the airfilter first, and then have the alternator and battery tested.
