I do plan to remove the sensor and clean it this summer. I read in this forum that there is also some sort of filter? I'll check my OEM Service Manual for that.

He wants to pull thaty and check it? If you disable EGR would that impact the performance?or cause stalling?

Replying to: crash227 (Jun 08, 2009 7:34 pm) Of course a visit to your local Jeep dealer , , one that has a qualified diesel mechanic , that can work on 2.8L diesels will fix that . This is a little Ferrari of Suv's you have , ad needs regular maintenance since our fuel is dirty and the engine was never adjusted to north American fuels . How to curb your visits , is to start using premium fuel , such as B.P premium , is my favorite, Sonoco red, Shell Ultra , or "Vpower" diesels fuels. Also you will have to start using additives , one that cleans injectors, such lucas formula, or power service. Stanadyne is the best . This will help your performance . Stay away from discount fuel.. all you end up with is an engine light and a visit to the dealer. And don't forget to pump your tires to 38 psi. This wil at least save you some $$'s and raise your mileage factor. good luck.. Lightnin

Replying to: crash227 (Jun 15, 2009 4:52 pm) It's funny usually guys get on here and complain about some problem they have. Well it's about time someone actually gets some performance out of her , other than me. Did you try pumping your tires to 38 psi ? , and how about using premium grade fuels other than the Flying J brand ?.. at the local truck stop.. I would like to see if someone can beat my average 33 mpg yet?.. . Where are you located ?. Do you have B.P. stations with Diesel out there?. if they do , the next time your on a road trip try a premium fuel instead. there are 2 different grades available , just have to find a station that serves 2 grades. B.P premium,Shell V power ultra diesel. , Sonoco red , Citgo #1 , Texaco premium. and so on. If you look around to the different "gas stations" that serve diesel , the better ones will serve a premium grade with a higher Cetane level usually around 45-50 points compared to the regular #2 grade diesel fuel with a cetane level of 40. I have been lucky to have access to Shell Vpower fuels here in Windsor Canada that claim that they have a rating of 50-55 . after using it I averageed 26 in the city and 33 on the highway. along with using the additives like Stanadyne cetane improver I have had the best results with this product. But when I can't get this , I use power service in the "silver bottle" that claims 6 point increase in cetane boost. Which I believe is a good product but haven't had results like Stanadyne.they seem to be the best product I have used so far. When I can't get these, I use Lucas formula upper cylinder lube and actually had good results with this as well . but not as good as a cetane improver. Also if your not on a long trip lets say an hour , why not experiment with your speed? . take your time in the right lane have space between the trucks , and set your cruise at 70 then decel to 55 mph . try to get your rpm's lower than 1800. On my best day so far I have reach 38 mpg ,I must have had a tail wind .. just make sure you have lots of space between the trucks and you when your on the highway . that way the speeders will see you in lots of time. I actually found travelling 70+ mph I lost on average 20% fuel economy. Well good luck hope to hear from you soon on your results after a tank full of the good stuff.. Lightnin.. Also utilize that over head console for the mileage and press reset when your at the 55 mph mark. and then reset the mileage counter and watch the mileage go up. It will give you incentive to slow down if your not in a hurry to get somewhere. that is.. |

| I have owned many turbocharged cars and trucks and I noticed something different about my crd. Most diesels I have owned have hard intercooler piping and most cars with turbos at least have an aftermarket options available. However I have found nothing for the liberty. Have you ever popped the hood and had someone rev the engine? It blows up like a balloon until that net wrapping stuff contains some of it. Is this normal or has someone replaced my pipes with some kind of sub-standard thin hose to handle the 25+psi air coming off of the turbo? | |
