Replying to: sthoge (Nov 06, 2008 12:16 pm) I have another issue. I had the starscan dianog on my Jeep a week ago. One of the codes that came back was an underpowered turbo. I asked if perhaps a clogged fuel filter might cause the code, they said it was possible. so I replaced the fuel filter. The Jeep ran better immediately; however, once I got about 15 miles down the road (running about 70mph w/ cruise control on), I would lose ppower going over overepasses: I had the cruise set  70mph and the jeep slowed down to 65mph -- normally, I would hit these overpasses w/ no lose in power. I can turn the Jeep off, wait about 5 miniutes and and hit the gas and the Jeep is quick and responsive, but after 15 or 20 miles 70 or 75mph is the best I can do. I push on the gas pedal, but I can get no increase in speed. My question is: is there anything that could be causing this besides a turbo that might be on its last leg? Would trash in the fuel line or injector cause this problem? I would like to try the "cheap" fixes first before invewsting $1,200 for a new turbo. |

Is your fuel tank well vented? The turbo vanes are driven by a pneumatic (vacuum) signal. There is a small filter behind the air filter box that lets air back into the vanes actuating cylinder. When this filter is clogged, the turbo vanes don't respond correctly. Usually the turbo lasts longer than the vehicle, but I'm sure there's more money to make by changing the turbo.

| We recently purchased an 05 Liberty CRD and really like the way it handles and it fits our desire to off road. After having a jeep dealer check it out completely ( on the computer) it has had all of the recalls taken care of and it does not have any warning codes that come up. As soon as we got it home we noticed a slight rubbing noise that comes from underneath. It sounds like a metal-to-metal noise similar to a dragging disk brake, not severe but just enough to be audible. I played around with the transfer case shift lever and shifted from 2W to 4PT and back again and it seemed to go away for a day. Then it came back again today. Has anyone had this same experience? I am concerned that it is doing some damage. This Jeep was towed behind an RV for awhile before we purchased it. | |

I haven't tracked this forum for quite some time. I have a problem which I am hoping may have been solved by another Jeep Liberty diesel owner. I do not drive my Jeep every day. In fact, it often sits for a week before I take it out. I am lucky in that my employer provides me with a truck which I take to work. At the end of the week when I have personal time and can take the Jeep for a trip, I have found the battery to be low and there is not enough charge left in the battery to crank the Jeep over. Has anyone else had this problem and have you discovered what was draining the battery? I have replaced the original battery with the largest battery that I can find and also keep this replacement battery on a battery maintainer which puts a constant low trickle charge through it. Glad to see this forum is still in existence..

Replying to: mdamick (Dec 15, 2008 11:28 am) Thanks for the response. I replaced the original battery at 36,000 miles with a battery larger than was originally installed (more amp-hours). I guess that was about a year ago. I do take the keys out of the vehicle when it is not being driven. I do have a trailer hitch installed. I will continue to use a battery maintainer in the cigarette lighter to assure starting on cold winter mornings. Does anyone have any other tips on assuring that my battery will not discharge?

Replying to: nescosmo (Aug 20, 2007 9:30 pm) Also, does anyone have a diagram or photo of where this "lawnmower filter" is suppose to be? What is the rue name of this device in the Field Service Manual? Should I umplug the EGR or should I clean the CCV / MAP and EGR? Anyone know of any good mechanics in Houston or Corpus area? |
