Hi there, we had a similar scenario.
1.) take your jeep to a local mechanic shop, dealers are ripoffs. Have mechanic replace the crank speed sensor located on the right side of the engine block. Hard to see unless its up on the lift. It's threaded into engine block with a 12 volt wire lead that goes back to the onboard computer. This sensor costs about 20 to 25 dollars at a parts store.
2.)Also have mechanic spray a can of carb cleaner into throttle body intake while engine is running. This will burn out most carbon deposits in throttle bottle and top of cylinder heads. Engine will stall out several times while doing this. Then have him pull the spark plugs if they look carboned up and nasty then replace them at about $4 each, will be cheaper at a place like Autozone. Also it wouldn't hurt to add a bottle of stp gas and carb treatment to the gas tank. Average cost for this job including labor should run about $125- $150.
Good Luck. Hope this works for you. It did for us.

HI i appreciate you writing back I just spoke to them I need $7,400 in parts alone.without the labor They said that I need 2 head cylinders timing belt catalytic converter, that the heads are burnt up. I am so stressed have been crying all day they said something about a speed sensor but never fixed it they replaced the oxy sensor and crank sensor,I owe them 488.00 for that Do you think it will run if I do that, as of right now I need it towed

Question for you on this Jeep liberty 2002 that you replace the Piston #2 and works fine.
Is it still running?
I have same issue #2 piston. It is sitting on my drive way to either fix or junk.

In spite of what the scan tool says, it smells like a bad EGR valve to me. Questions to pose to you are:
1. Do you "blow the egr valves nose" on a regular basis, in other words do you with a fully warmed up engine and from s dead stop and with overdrive locked out, stomp on the gas and blow out all of the accumulated carbon from the engine?
2. Do you do lots of city (stop and go) driving or mostly highway driving?
3. Are you still using the Mobil 1 0W-40 garbage oil?
4. Do you clean the boost sensor at the back of the intake manifold on a regular basis?
5. Do you use any fuel additives or cetane improvers?

Hi they say something with piston # 3 I have not done a thing with it yet it is just sitting also, The dodge dealer wanted called back and wanted $7,400 for parts alone for that amount of money It is ridiculous you could get a junkyard engine or parts. I will keep you posted, If you look at post #95 this sounds like something to try before anything,

Hi I always use Mobil 1 I also put a gas additive in it, I do a lot of city driving stop and go, I never let the engine warm up and always ran the car with very little gas which was why I went to get the fuel filter fixed and they replaced spark plugs $200 and then had oxy sensor and crank sensor replaced $488.00 and it still will not start. Oh also some times when I did try to start it it sounded like a huge backfire under the hood like a gun shot or backfire but under the hood, I am so frustrated at this point the dealer wants $7,400 for parts alone that is without the labor. I am desperate, Not only that our other car a 1997 jeep wrangler the hose came off and the needle did not show the car was running hot but the car started driving crazy there is oil every where and tapping noise so loud when it did start and that is dead also all of this happened within a week of each other

I just read the definition on the EGR valve it is exactly what was happening when it ran the bucking and the shakey idle I will check into this
I don't know much about cars

Based on the name you use here, I was under the impression that you drove a Jeep Liberty CRD (diesel),
First of all your driving habit, mostly city, is contributing to the problems you are having. City driving is the worst thing you can for any engine. Not letting the engine get fully warmed up is bad news too as you will have issues from moisture accumulation as well as carbon buildup in combustion chambers and elsewhere.
You need to get your Jeep out on the open road and run it fairly hard for a couple of hours to drive out accumulated moisture and to start getting rid of the carbon buildup.
Looks like you have a mess on your hands. Try someone other than the dealer. A second or third opinion does not hurt. Good Luck!

Ok Guru's 2006 Liberty 2wd 6 speed 31,900 miles check engine light just came on. Checked the code on the odo. all it says is 6.3 before it displays 0.0 for trip miles. Jeep has been a great car. Only problem to date has been L/R window, but found a metal part on line and was an easy fix. I have been recently getting a noise in the R/R wheel when braking so I'm thinking new pads. other than that has been fine. 6.3 for a code seems strange, any thoughts on this?

Well your repair issues are not a BIG deal for any backyard Mechanic..For probably a 1/4 of the dealers cost. I have NEVER (in 35 years of car ownership) let a dealer touch any of my vehicles UNLESS it was covered by their warantee...Hell I find with patience and a bit of time I save THOUSANDS $$$
For me...If Ive never repaired it before..Doesnt matter, I DO IT MYSELF and learn on the fly...If you think real hard Ill bet you can find a male friend who is Mechanicaly inclined or better yet fairly experienced...pay them to do the job.... At This point you are gonna pay the dealer more than the vehicle is worth. My dainty and mechanically challenged wife replaced her O2 sensor for the cost of the sensor $50.00 and about 35 minutes of her time most of that time was reading the manual.
