The Jeeps are OK but poor marketing and lacklister mileage numbers plagued them. Not to mention the premium to get a CRD over the gas engine. ie., It wasn't worth it. The only problem with the 2.8L is the ERG valve. They are prone to failure and are expensive to replace. I think there is a way to disable the EGR part of the ECU with a re-flash.
