JEEP LIBERTY CHEROKEE 2003 Jeep Liberty 3.7 very high petrol consumption

Hi everybody I have a jeep liberty 3.7 2003 with very high petrol consumption. The car consumes between 10.5 - 14mpg but it doesnt matter if I go slow or fast in traffic or open road it stays the same no matter what. Some days it decides to consume around 10.5 mpg and others it can go as much as 14mpg but not much better than that. The engine light has been on for some time now. The auto technician

First off you have a jeep - bad fuel economy is part of the deal. Youll be lucky to get much better than about 17mpg. Sorry to be blunt but if you didnt want heavy fuel costs you shouldnt have bought an American vehicle. For various historical reasons mainly related to cheap gas prices in the USA American cars are notorious for higher fuel consumption than equivalent European or Japanese cars. Secondly

Last tune up Spark plug choice & interval changed are a big part on liberties...Id say on avg for a stock Libby you should be around 15-17 city depending on driving habits and conditions. Edit No chips period. And if youre not familiar with cars talk to a friend or family member and get a recommendation for a shop to take it to. For a technician to tell you it could be O2 sensors catalytic convertor

JEEP LIBERTY CHEROKEE Petrol to Diesel

Hi All Im after some advice I want to convert my cherokee jeep 3.7 auto 2003 (uk Model I believe its called a liberty in the us) to diesel. I have done this sort of thing in the past so I have some experience. I have some questions.... Is it as simple as changing the engine and ecu unit Can I use the same fuel tank I assume I can Whats the best diesel engine to get Will the engine fit straight onto

Hi Thanks for your suggestion but why do I have to change the trans cvs etc. I would have thought the that the running gear is the same. I relies the engine ecu engine wiring filler neck will need to change. Im sure the clocks have the diesel lamps and the engine wiring will plug into the the existing loom once Ive unplugged the petrol wiring loom. So has anybody done this or works on them and would know..... Thanks again for you input........

I really hate it when I have to agree with you TJKJ... Unfortunately he is exactly correct. The transmission might be the same but the front suspension is different to accommodate the much heavier motor. The engine computer and transmission computer are different (separate) unlike in the petrol version. The Body computer is also programmed differently. The dash cluster is different as well having extra

JEEP LIBERTY CHEROKEE Engine speed problem

Hi I have a 03 liberty Sport (2.4 petrol) UK spec. Recently it has had a new head gasket and the cylinder head skimmed due to it overheating and breaking down. After it has been repaired there seems to be a miss on the 2nd cylinder in idle and when decelerating the engine speed drops dramitically and almost causes the engine to stall. The mechanic has installed a complete new set of spark plugs but

Update on this.. It seems that the engine miss has returned. I had another look at the ignition coil yesterday and again the 2nd Cylinder terminal looked off colour when compared to the others. I gave it a clean but still no luck this time the miss is still there. It looks to be the 2nd cylinder that has the issue with the spark plug to this cylinder being black and dirty compared to the other 3. One thing I forgot to mention before is that the battery light came on due to having the hazard lights on for so long. Could my battery be the issue Would this not affect all spark plugs and not just the 2nd cylinder one So here is a list of work already done. Cylinder Head Gasket replacement and Cylinder head skimmed. Oil and Filter changed New set of spark plugs Compression test done on all cylinders and compression check is fine. Checked the HT leads and they seem fine. Not tried the swapping the injectors yet. Not sure how easy this would be. Again any help would be greatly appreciated Cheers Nige jeep cherokee 2.4 Sport UK Spec petrol 50k mileage

JEEP LIBERTY CHEROKEE Inability to fill tank with petrol driving me round the bend

The nozzle cuts out every 10 seconds whilst attempting to fill up at the petrol station is there a problem with my car or is this a regular occurence with cherokees (I have only had the car for a couple of months) PS there is an audible sucking sound after the pump clicks off as if air is being released after which I can commence filling yet again takes 30 tries to fill her up like I said its driving me (and the missus) crazy Hello by the way a new forum member from London UK 1st post

The ORVR (On-Board Refueling Vapor Recovery) system is used to remove excess fuel tank vapors. This is done while the vehicle is being refueled.. Fuel flowing into

I occasionally got that problem with filling up mostly in the first couple seconds. I thought it was a problem with their pump. There are some fuel lines under the drivers side in the US version that look like return lines. There was a small section of hose connecting the two sections right around the transmission area this was very cracked and almost falling off on my jeep. I replaced this line easy

JEEP LIBERTY CHEROKEE Engine light came on

My Wife has a 2005 JK. At over 120K it is in great cond. All new tranny fluids etc... and no leaks But one fri afternoon after she fueled up and the engine block appears The Book says it could be a bad cap or bad gas. Well unlike me she uses that Ethanol crap gas all the time. So I started fueling her jeep with real gas with the Lucas additive. I unpluged the battery terminal to reset the OBCcomputer. After 150 miles or more no more codes lights. Did the better gas with Lucas fix the prob

Hello 1) I was lead to a website which listed every 100% gas gas station in the USA. Every one visited was closed. South from NYC into So. Carolina and west from the same point to Nashville TN.

JEEP LIBERTY CHEROKEE Why did you buy your Liberty

You could have chosen any jeep that has been created from Wranglers to the FC trucks. But you decided to buy a jeep liberty. My question is why did you select this vehicle and if you could do it all over again would you change a thing Ill be the first to answer the question. I totaled my first vehicle a 1997 Nissan Pathfinder around 2007 due to inexperience. I needed a new vehicle so I could attend

I bought my CRD liberty because roads are a mess here in my country (i live in Chile and specially after the earthquake) and gas (or petrol) is much more expensive than diesel. (gas is 2.1 USD per liter) I think you guys in USA dont have the diesel version because it has a problem with emission standards. A little bit noisy yes. But nothing serious. I installed an ipod integration kit I recommend it.

Whats the latest news on the diesel powered liberty Its getting hard to wait.

I have a 2.5 CRD and have driven the 2.8 CRD. Unless you have lived with the sound of a oil burner before you may be very disappointed its not as nearly refined as jeep would claim. The fuel consumption figures they quote are wishful thinking as well If you like covering the cars behind you in smoke as you pull away from the lights then the CRD is the one for you.

JEEP LIBERTY CHEROKEE Switching to Synthetic oil 1 question

I bought my 06 Lib Sport V6 used with 17k on it. I want to switch over to syn. Should I flush the whole system with syn and then fill it with syn before using it Thanks alot....

oil analysis is the ONLY way to extend beyond highest recommended OEM oil change intervals. It is true that quite a few SEMI owners have gone into the 300K range without changing the oil but that was with bypass filtration and oil analysis. Amsoil recommends changing at the HIGHEST OEM interval unless oil analysis says you can go longer. For the CRD that is 12500 miles. Ive got an 06 CRD liberty

JEEP LIBERTY CHEROKEE oil chage

i have a 05 liberty renegade and i would like to know if mobil 1 extended performance is good oil to put in my car its full sinthetic 5w 30 and also i have skid plates off road package do i have to take off any plates to change the oil filter

before using the full synthetic. . The Corvette and Viper both come off the assembly line with synthetic as do many European cars. The tolerance in modern engines is a great deal tighter and requires less break in. What you dont want to do is change a tired old engine over to synth after a hard life on petroleum based oil. Ill do the first oil change at 1500 miles and go to synthetic in the jeep.

Hello CRD owners My dealer (Owner friend of mine) received a new CRD Limited on Fri and gave me the keys to use over the weekend I was very impressed with the performance and quality.

I have done two extended runs in my CRD in the last year. In the first I averaged 28mpg over 800 miles of mostly highway driving.

JEEP LIBERTY CHEROKEE Using Biodiesel in 2006 Liberty CRD

Hello Everyone I have a question. We just got our 2006 liberty CRD from the dealer and I asked if it was ok to use biodiesel in it. They told me no because some other people had problems using biodiesel. They also mentioned that theres some computer chip that needed to be swapped out in order to use biodiesel. I was wondering if anyone had any insight to this. I specifically purchased this liberty to use biodiesel in it (or make my own) so it would kinda suck if I couldnt do that. Thanks Tim

Some interesting info on ASTM D 6751 Quote The Biodiesel Standard (ASTM D 6751) All engines are designed and manufactured for a fuel that has certain characteristics. In the US the industry organization that defines the consensus on fuels is the American Society for Testing and Materials (ASTM). In the case of diesel fuel (and biodiesel) the responsibility for setting standards lies within ASTM Committee

JEEP LIBERTY CHEROKEE Diesel Liberty

I just came back from test driving one of these things. Man that thing is a torque monster. Only hangup is it sounds like a tractor. Actually the salesman said that it is the same engine as some tractors. Its for my wife but I think I could pull a few stumps with it. 295 ftlbs.

The CRD might not be for everyone but after having one in the family for 6 weeks we are pleased with it. Its the family 4 door grocery getter and future baby buggy. Sounds like a tractor Well it is a diesel so youd expect engine clatter compared to a petrol engine but once warm and crusing at high speeds you cant even hear the engine which is better than I can say for some gas engines. Its got good

JEEP LIBERTY CHEROKEE Thinking of purchasing a 06 Liberty CRD

I am seriously considering purchasing a 2006 liberty CRD and have some questionsconcerns regarding the diesel engine. First I have been told by several dealer service techs that the CRDs operate best when used primarily for highway driving as diesel engines take awhile to properly heat up and running them at higher RPMs for long periods of time helps keep the throttle bodies and injectors clean. Most

The CRD engine is brilliant and cannot be linked or blamed for torque converterball joint brake pedalor transmission faults. This engine is also fitted with a viscos coolant heater and believe me they warm this engine fast. Also you will find they are fitted in the famous london taxis and the ldv maxus van range not with highway use only in mind.they use Bosch injection equipment any diesel tech will understand.NOT throttle bodies like petrol engines. buy one you will only need service items.

JEEP LIBERTY CHEROKEE Is the CRD worth it in fuel savings

Has anyone done the calculations to see how long on average it would take to recoup the premium you pay for a diesel over gas

There have been pictures of a longwheel base Wrangler (longer than unlimited) which jeep are trying to sell to NATO which has a single fuel policy. If it aint diesel then NATO wont buy in to it so maybe you wont have to wait that long. Apparently the Hummer got a bit of a slagging from troops in afganistan as it was not able to handle the trails (too wide). In base terms the CRD is not worth the extra

Any help is appreciated. Thanks.

PL25230 or L25230. Local store had it for 5.99 and Mobil 1 0-40W was on sale for 3.99 ea. So 7 qts and filter cost about 34. .

This can be really important especially when you are buying accessories for your jeep.

JEEP LIBERTY CHEROKEE CRD-issapointment

I went and test drove a CRD today. I was shocked that the power was lacking so much compared to my cherokee 4.0 or even the 3.7L for that matter. Ive heard so much about this truck. I can only imagine how much worse it gets when you fill it with vegetable oil. I hope DCX rethinks this strategy. Maybe the Escape Hybrid is the better choice if all were trying to do is save on gas...

Fuel economy seems close although I have not done exact tests - as my driving patterns are not the same all the time. But we average about the same no matter which fuel we use.... Your driving style will impact the fuel consumption much more than the use of Biodiesel. Does biodiesel provide similar miles per gallon torque and horsepower as petroleum diesel I have to say with only B50 in my jeep there is a noticible differance in power like 10-20% and I get .5 MPG less also.

I just want to put this out there. For the longest time I had the annoying p0093 error code and the jeep would go in to limp mode often. I spent countless hours troubleshooting and online forum surfing. The symptoms were as follows. Runs fine cold. Once it warms up it gets bad gas mileage(21-22.5mpg) limp mode often(always at the worst times) sometimes ran hot smokes under hard acceleration sometimes

I just want to help anyone with startingrunning issues so they dont have to go through what I have.. I have read countless threads of people having similar issues with no fix. If you are having any drive-ability issues(cold start hot start limp random codes p0093) I would start with the injectors. Have them tested. Replace that filter with something better.

JEEP LIBERTY CHEROKEE Diesel at 3.45 a Gallon Is Buying the CRD a Mistake

I think so folks. My 2004 Corvette is now CHEAPER to operate than the CRD is. Shell V Power here is selling for about 2.89 and regular 2.65 a gallon. My Corvette averages about 23 MPG in mixed driving. If Diesel prices dont decrease soon I will be DUMPING the CRD in a HURRY. I see NO advantage to buying the CRD as long as diesel prices hold the current pricing of being nearly 80 cents a gallon higher than 89 octane unleaded gas.
