Replying to: lightnin3 (Jun 02, 2009 9:58 am) Just to add some supporting evidence that 38 psi is about right for fuel economy, at 65k miles my OEM tires are not completely worn out yet. Even at 38 psi the edges have worn faster than the centers of the tires. I'm not sure what reasons the manufacturer had for recommending such low tire pressure (What was it, 33 psi? Don't care really.), but it was not for fuel economy or tire life.

Replying to: siberia (Jun 07, 2009 6:55 am) I just changed my winter tires over to the stock wranglers . It has been 4 yrs now , I have been switching my tires .Having a second set of tires and rims really paid off. It was one of the areas the company cheaped out on . maybe to bring the cost down. Thats' why they give away Liberty's on the lots so cheaply. Rubber costs $$'s. Yea I think , I actually gain about 2 mpg just pumping up my stock tires, compared to the mudder lugs.. They were only to have a 60 K km's range anyway. You know it's funny a lot of people complain about their mileage in the winter monthes.. on here , but when I suggest a few tips , they never reply and say how they made out?.. hmmm. I wonder if they realize ..oh darn !... I have to drive slower to get better mileage and buy decent fuel.... it is only common sense..really. I find the biggest mistake people do is speed . They are always in a hurry everywhere. Here in Windsor and all across Ontario we've had speed traps , so it is an incentive to slow down. I just do the "use the cruise " method and it works both ways.. So watch it, if you plan on coming for the air race in WIndsor ,or fireworks display for the July 4 th weekend, or maybe your planning on going to Toronto for a party, there isn't any allowance for speeding and they really soak you now. Cheers.. Lightnin.. |

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.

Replying to: mdamick (Jun 05, 2009 9:31 am) $200, but did not clear the CEL. Now he wants to pull the EGR and check it. Do you know who could disable the EGR? Do you think the dealer would do it? He wants to pull thaty and check it? If you disable EGR would that impact the performance?or cause stalling?

Replying to: kesh25 (Jun 10, 2009 1:23 pm) In my case, the EGR caused poor performance and stalling. They will either clean it out or replace it which will work for a while.

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
