I do have a 2000 XJ throttle body that I am willing to send in. Send me your info and I'll be sure to get it out to you tomorrow. I threw out the box it came in just in case you were wondering.
i installed my new TB sunday and here are some first impressions.
- installation was easy-peasy, plug and play. this can be/was done within 10 minutes by an idiot.
- quality work. this thing looks brand new, clean and smooth. i'm almost ashamed to send my junk original back to this guy.
- quiet. no whistle under any level of acceleration
as for performance, i'm not sure about any power gains. i think it's got a bit more giddy up from a stop but i may just want to feel it. i can definitely say that the power seems smoother under acceleration if that makes sense. also, though it may be related to cleaning my IAC and running a can of sea foam through the tank, my RPM's have dropped across the board. idle RPM went from 1200 to around 800 and cruising through town around 45mph i'm at 1500-1600 instead of 2000. if this is a result from the TB, i could definitely see where this would affect the fuel consumption. i'll report back after i've gone through a few tanks and let you know if i see anything worth while.

Also it is worth erasing the old ECU or PCM memory.
- Disconnect the POSITIVE battery Terminal and touch it to ground for 30 seconds. (This is to discharge the PCM capacitors, which maintain the Adaptive Memory.
Reconnect the Battery Cable
Turn Ignition Switch to the “On” position but DO NOT start the engine
Turn Headlight “On”
Turn Headlights “Off”
Turn Ignition Key “Off”

If I down my 95 XJ and send you my tb, does this mean you will turn it around without having to put me on your list? Appears you are putting a good product out (read the whole thread) and sounds like a good deal.
