Jeep Liberty diesel fuel mileage
A friend has a 3 yr. old Liberty CRD diesel. It has recently started blowing more black smoke than usual and the mileage around town has dropped dramatically (10 mpg). I have had several diesels but haven't owned one for ten years so my thinking my be dated. However, the drop in mileage and excess smoke used to usually indicate an injector issue. The dealer keeps telling her that nothing's wrong but cannot account for the drop in mileage or the excess smoke. Actually, the dealer seemed completely clueless. Are there any addictives that will clean the injectors (or is that "old" thinking) any other suggestions?. The car is low mileage (30,000) and she likes it except for the problem with mpg. The last time we took it on a long trip, highway mileage was o.k. -- about 27 mpg. Any thoughts would be appeciated. Thanks - Jack Weber

Have a 05
Have a 05 and love it. But have had EGR issues, which was covered under the extended warranty. The dealer that I bought it from, Jeep pulled there dealership, and the Jeep dealers that I talked to was clueless when it came to the CRD. I did fine a mom and pop dealership which is 50 miles away from where i live but they do all my work on Lil" D ". Seems like the bigger dealerships are not geared to customers but money. Have done some mods and in the process of installing a programmer. I'm talking to 2 companies. But am swaying to 1, they can detune the EGR and other mods ,as needed, not cheap but you can return the EMC to stock if needed. Not pulling the ECM and sending it to them to reprogram. Getting 25 to 30 mpg. Will post after mod is done
