Just bought an '06 Liberty CRD with 80k Monday last week.
This is one of the FEW sites where good CRD info has abounded, and already put to use.
(yea, I have read the noob guide) cleaned a completely plugged sensor,
and ordered an ECO..
many thanks to all!
My dearest wife has recovered from having two accidents in a single week,
and I am now dealing with the insurance co & repair estimates for #2

(#1 terminated our 01 XJ in a walmart parking lot

,
and put us into the 06 KJ)
More on this saga to come..
