Thanks to everyone who helped me solve the Idling problem, I DL'ed the Rave manual and get the IAC valve out and gave it a good scrubbin and then cleaned out the throttle body, She now runs at a cool 750-900RPMs at idle Gosh i just love my LR

 

Should be at the 725 range when at operating temp, 900 is too high.

 

Glad your idle problem is solved, but like Mike said the hot base idle is closer to 600 rpm.
Anything below 550 and she will stall, to high and you waste gas and its hard on the drive line.
Make sure that the A/C is off to see what you hot base idle actually is.

 

So now that you have figured out your idle problem it's time to get the 60K service list done if you haven't already. Maintenance on these trucks is never ending if you want it to last.
