have a Jeep Liberty Diesel with about 1000 miles on the clock. I like it but I have had a couple of problems with it. Twice when after filling up and having done about 20 to 30 miles then stopping, when I get in again to start the truck it will only run on about two cylinders. The vehicle will slowly creep through the gears and feels like it will stop any moment, clattering and creeping along. I stop and turn the truck off, phone the dealer who will ask me to get it back to the dealership. When I go to try and take the truck back it runs perfect and the dealer can not find what the problem is. Here are the details: I fill the truck when the fuel light comes on. When the problem occurs no lights come on the dash and the dealer says no problems are showing on the computer. Have any others experienced this problem and has anyone any idea what it could be. Regards Nickaway
I noticed the same problem with my CRD. I'd been driving at a steady 60 mph, I stopped to get an item from the back, and when I restarted it, it did exactly as you described. I pulled over, shut it off, checked under the hood (all OK) and then restarted it. It ran beautifully. No check engine lights came on, and it had 1/4 tank of fuel. This is the first time this has happened, mileage is 2000. Let me know if you find out anything new about this. I've had air in the lines in other diesels and it did not sound like this. It felt more like a computer malfunction, especially with the restarting beautifully. The other computer diesel I had, a GMC 6.5, acted this way when the computer went into the "limp home" mode.
CRD Limited, use standard diesel with Stanadyne Performance additive, and have a Mann Provent installed.
