Replying to: Mr_Shiftright (Aug 01, 2008 3:06 pm) Yes! the jeep Liberty '05 runs very well on store bought diesel fuel. This must be because it was designed to do so. The problem is that it stalls on centefuse cleaned oil that it and other diesels are running on. Could the common rail not create enough suction to pull fuel through the fuel filter? Could installing an auxellery fuel pump solve this problem? Is there a fuel filter that would let more fuel get to the motor? I am open to any suggestion. Yes another expert said I could trade to get another diesel.
#99 of 158 Jeep bogs out after sitting for long periods by grammaging Sep 01, 2008 (2:31 pm)
I've been reading about the problems others are having with their liberties. With mine the same problem happens. We just went on vacation and the jeep sat for 6 days. When we came back and tried to go shopping as soon as the jeep reached operating temp, it bogged out and the RPM's won't go over 2000 without the jeep chugging and can't travel over 30mph. My husband has used carb cleaner which was a temporary quick fix. He has replaced one of the oxygen sensors and just today replaced the throttle control sensor. No dice. still the problem remains. Anyone know why this is happening when the vehicle sits too long or is that just coinsidence. This is very frustrating. thanks Replies to this message: johnhayworth (Sep 02, 2008 5:37 am) mfitzyk (Sep 09, 2008 6:56 pm) eamm (Mar 02, 2009 8:37 am) grammaging (Mar 02, 2009 9:20 am) steve_ (Mar 02, 2009 9:57 pm) eamm (Mar 18, 2009 3:05 am)

Replying to: grammaging (Sep 01, 2008 2:31 pm) First: Has your fuel filter been changed recently? If not DO SO! Blwing the nose of the CRD. Take your Jeep out on the High WAy where you can go fast. From a slow speed excellerat as quickly as possible . You should see a clowd of black exoust. Afetr several axcellerations the black shouldc go away or turn white. This is a fix. Get some biodiesel it will help. This works fore me. Pardon the sloppy message as I must hurry to work.jdh;-)

i'm having that sam problem where after around 20 minutes of driving it wont drive anymore when you press the gas it just wont go!, the power stays on it jerks then shuts down.. when you watch the RPM the do a dance back and fourth.. I can restart it only one time : buy raving the gas then it will only go about another 2 minutes before it wont even click to start.. i know its not the crank sensor because it has been replaced, the battery has been replaced also, injectors have been cleaned, carberator flushed i'm still at a loss. PLEASE HELP!!!

Replying to: grammaging (Sep 01, 2008 2:31 pm) We owned a 2005 Jeep Liberty for about 3 months before getting so frustrated we traded it in. There was ~50K miles on it, same problem. On a 2-3 mile trip the Jeep would stall out. Would have to restart it, would sputter, sluggish acceleration, stall. The dealer we bought it from was a crook, so we took it to the school's auto shop that my wife was teaching at. Instead of replacing cam/crank sensors, which is what the error codes stated had faulted the engine, the master tech the school suggested cleaning out the throttle body first. For a $7 can of throttle body cleaner, the problem was solved. Obviously labor was not included as this was a school run program, but this seemed to fix the problem. If you read up on this, it should be something you can do on your own. For the next couple of weeks we had the Jeep, it no longer stalled, which was previously a daily/multiple times per day phenomenon. Ultimately we sold the Jeep (have never been happier with our new Explorer). The way the mechanic explained it to us, because of new emission standards, some of the exhaust is brought back through the intake/throttle body apparatus leading to heavy carbon deposition (our throttle body was heavily carbonized), which leads to decreased air/gas delivery to the engine causing it to stall out. This should not happen highway speeds because of the higher RPM's and inertia of the engine and relatively lower gas/oxygen demands. If you think about it, engines require more fuel/oxygen during high demand..i.e acceleration. Your engine is not going over 2000 RPM because there is not enough fuel/oxygen getting delivered to the cylinders for adequate combustion. The symptoms are worse when the engine heats up because as the air gets hotter it is less dense meaning there is less oxygen to help burn the fuel again causing stalling/sputtering/sluggishness. I would do one of two things:   1. Clean the throttle body or better yet - 2. Sell the Jeep

Replying to: rashaw (May 27, 2008 5:58 am) Thanks for your input on the Jeep stalling problem. My husband and I viewed the many suggestions people sent in. 2 years ago he tried spraying carb cleaner into the throttle body intake. it was a quick fix but short lived. As soon as we went on vacation last year and the Jeep sat idle for a week we had the same problem. So he went with the quick fix again. It ran great. This year after vacation; same problem, only this time there was no fixing it, so this time he thought it might be the throttle position sensor because our other Jeep had that problem. Unfortunately it didn't help, so I found this forum and showed him some of the entries. After reading yours he took the Jeep to our mechanic and he hooked up his hand held computer and it displayed the message crank shaft speed sensor. We ordered the part and had him install it. That was about 2 weeks ago and so far not a problem. It's running great. So if anyone out there is having these problems with their Liberty stalling it may be that sensor.

Replying to: grammaging (Sep 13, 2008 3:22 pm) The error code that probably displayed was P0320 (you can call your mechanic and see if he remembers). It is a completely generic code and all that means is that when the cam or crank (for the valves/pistons in the engine repectively) stop in an untimely fashion (i.e from stalling) and not from turning off the key (like it is supposed to work), then those sensors will send an error message to the computer stating that those sensors "faulted". To replace a $100 part because of a "faulty sensor" should, in my opinion, be a major recall by Jeep since you, me and thousands of other people have had this problem. But perhaps you're right and the sensor failed and I got lucky with just cleaning out the throttle body. Since this has been such a big problem for so many people, it is my opinion that Jeep should be held responsible for all of the repairs, whether in the end they were needed or not (i.e. recall).

Replying to: mfitzyk (Sep 13, 2008 11:48 pm) I agree. I am still amazed at the numbers of us who endured. And you are right about the generic code. The first time this happened I took it to the dealer and after paying $80 to connect to the computer a "P" code came up. Can't remember the #s. This time with the hand held it actually said crank sensor on the screen. I think we should complain to Jeep about this because our Jeep only had about 30000 miles on it when we first had the problem.

Replying to: mfitzyk (May 26, 2008 5:38 pm) Can someone please tell me HOW TO clean the throttle body. I am a beginner and have no idea where anything is. Thanks in advance!
