I have found weights from 4795 to 4985 for the Grand Cherokee. These values are from foreign as well as domestic publishers.
Rather interesting that the Jeep website gives the weight you have. The Liberty is around 3650 lbs. In the magazines, the Liberty CRD is around 4300 lbs.
3994 seems to be the number for most of the 4WD models at Jeep.com and we must get our info from the manufacturer, because we seem to match. Options will change that info too.

Similary, I've been having the Cummins engine in my Dodge pickup serviced at Cummins shop.
The 3.7 L V-6 has a cast iron block as does the four cylinder last put in in 2005.
If you change the settings at the top of the page to 4x4, it shows their curb weights, with a basic of 3851lbs for the 4x4 with stick shift, but that leaps to 4033lbs for the automatic transmission (gas V6 in both cases). I'm wondering if the auto weighs an additional 180lbs all by itself, or if it comes with other features that push up the weight. I suspect that any upgrades (transfer case, wheels, stereo) push it to the 4100lbs curb weight that I've seen quoted elsewhere. I'll be curious to hear what your CRD weighs on the scales.
Thanks for the tips! I'm already doing some of that: Shell premium diesel, cetane booster, tire pressure 38 psi, reasonable speeds. But still only 19-20 mpg.
At 3.2K miles, maybe it will be time soon to change oil and filter. Since it got hot here in Texas I have been running the A/C more, so could be part of the problem.
Thanks,

Sorry, way too complicated and bothersome to be useful. If I had to baby my CRD that way, I would get rid of it yesterday. The chances of me driving slow, changing the oil every time it rains, or making sure the tires are so hard that my private parts clank with each bump is non- existent.
My solution to the mpg issue is simply to wait until you have over 20,000 miles on the vehicle. My mileage has gone up as the diesel has gotten "looser" (probably tranny too). I get 25+/- mpg @ 75mph with about 26k miles. If I do alot of "in town" driving my average falls to about 23 (not that there is a lot of city driving around here anyway). I use the "evil" 0w-40 oil the dealer puts in and I don't even look at the air filter till 12 miles has gone by.
Remember, its just a car-drive it, or sell it, but don't whine about it.
Here is the link to the newer glow plugs:

Look elsewhere. You might need to consider switching fuel and/or adding a cetane improver and or injector cleaner. Look at the air filter. I changed the original at 7500 miles as it was totally filthy. Are the brakes binding? What MY is your CRD?
I think if you keep your Ram up you might just have a truck that won't depreciate much.

I think if I want to complain about my CRD then I have the right as I have one.

I am not sure where you got your numbers, but they are very wrong. You can call DCX at 1-800-992-1997 and ask for yourself. They do have the 2005 numbers, and your dealer can give you the final total for CRD's which stopped in early May.

Since this engine doesn't have a heavy flywheel to help producing heat created by compression + angular speed, it needs a longer glow time to make shure ignition continues after the initial impulse and when the starter motor is turned off. I remember reading in the manual that our plugs keep glowing at least two seconds after the engine has started.
Another converging info from the ECU documentation is that the starting of the engine is controlled by the ECU alone, and gives hand to the driver only when a soft running condition is obtained. This starting condition measures the acceleration of the engine after each injection pulse and adapts to individual cylinder wear. This is sophisticated but needed to replace the inertia of a flywheel.
The nasty thing is that glow plugs can be turned on without producing their nominal temperature. This was often the case on older models after ~20,000 miles. There is probably a set of OBD codes pointing to a 'non successful' cold start.
"10,313 diesel Liberty's sold in its first full year in production."
Maybe it's a wordsmith article. It does not state how many, if any, 2005 models were produced in late 2004. It does not state that this number is only for 2005 models, so probably includes 2006 models made in late 2005.
Still, there has been more than 700 made this calendar year, no?
I'm trying not to let the 11,000 total production number sink into my head...
I believe parts will not be a problem either. Hopefully techs won't be. What I disccerned from the jeep website was the implication that CRD's would in fact be produced in the libby and wrangler here in the USA, but only for export!! So parts should be available for quite some time. Even though my 05 Libby has 100K warranty on drive train, I bought the extended for everything else!! It could be real cheap insurance or a waste of money. Either way, I have peace of mind. Also know a lawyer who was lead attorney in a $75 million class action settlement with Honda about 10 years ago, so if DC does'nt take care
of issues, he has a good chance of "encouraging" compliance.

Don't ask me why P0403 is there 3 times :confuse:
If the word airflow is mentionned in your case, it should be the flap not closing completely or the end-switch out of position.
I checked on another site and it says exhaust flow instead of airflow. In this case the lambda sensor detects too much oxygen :shades:
Since you measured your voltages with a scope (very high impedance), you may have detected a false contact or high contact resistance on your plugs that can only pull more current after the surge has happened and re-melted some kind of contact. You must have a load on the controller to let it regulate the voltage.
Now if the controller went wrong and sent the full voltage to your plugs, this could explain the two 'open' circuits.
What you could do to put the controller to a test is to connect 4 individual headlamps to the unit and see if they give the same illumination.
I would also check the engine grounding cable/strap. If there is an intermittent contact (loose connection) this can create problems to the electronic modules by swinging the voltage up and down

You must be doing something right.
Thanks for the heads up Winter2 ..I agree with your input always.You seem to be a veteran at owning a diesel.
Yes definitely check the air filter.
I just did mine and she has about 30K miles on her.Not bad for a 1 year old ,but the filter was dirty..dirty...Then I got a brain wave and bought a K&N filter.
I seriously wanted to try it ,to see if it would make a difference.I have been getting
28-30 mpg 450-500 miles/tank ,more consistly now,on the hiway.
CRDblzr..If you do an oil change ,I believe you'll notice "some" improvement in the performance,but patience is needed for the break in period.Diesel engine are very tight until broken in.
But Like Winter2 noted,check the air filter to see if it is Ok..
Also start using an upper cylinder diesel fuel additive,or a cetane improver that has injector cleaners in it.
I use Lucas formula,and have seen better results,plus it's piece of mind to know that your injectors are getting cleaned.
I have heard that Texas diesel fuel is very dirty and poor cetane levels have yielded poor mileage.
I would keep on buying the "premium" ,but try experimenting with other brands like B.P.,Citgo,Sunoco ,Esso,
you may find a difference.Maybe a truck stop,Flying "J" ?
is near you..
Hopefully ULSD will be out soon,in your case.
We are patiently waiting as well,
but I have heard that Bio-Willy is gaining ground in the Bio- Diesel dept.
Has anyone tried this fuel yet??
Is it worth buying??
Speak Soon..

1. Smoother idle.
2. Quieter, less knocking and nailing.
3. Unchanged FE
4. Acceleration same, but a little less smoke. Hardly have any of that to begin with.
5. A slightly lighter wallet versus purchasing straight #2.
I got 480 miles on my last tank, but it was just a little above 24.4 mpg. So my opinion is you must have used less than a tank to go 450 to 500 miles, I hope.
So far here there is neither ULSD or premium diesel near me. In fact the only Bio fuel is B-2 and the nearest station is 2 hours away. But diesel has gone from $2.639 to $2.899 in less than one week while gas only went up a dime. The E-85 is $2.239 which all of a sudden was there at the pump last week where to kerosine use to be.
I am not picken at you Lightnin, and I hope you will see it is sorta funny the way you presented the facts. Hang in and maybe there will be a night math school near by you.

I use B20 whenever possible and I have experienced #1-4. The engine is a lot happier and quieter on B20. Fuel economy doesn't seem to change up or down and power is about the same. However, with petrodiesel being $2.89-2.99 locally, B20 is generally the same price or in same cases even 5 cents less than pure dinodiesel, around here in lower Michigan. I am very happy with B20. Added bonuses are that it has much better lubricity and contains 20% less sulfur (no sulfur in the bio portion). Smoke is nonexistent on B20 and the smell of exhaust is less unpleasant.
We do not have "Bio-Willie" around here but my understanding is that it is just B20 soy biodiesel, so it should be identical to what I'm using.
Some have had problems with biodiesel but I suspect these are all due to improperly made biodiesel. Quality still varies, though locally I have had no problems. Poorly made biodiesel may contain water, glycerin and/or methanol, all of which are very bad for the fuel system. Properly made biodiesel has negligible amounts of glycerin and methanol, and low, tolerable amounts of water (typically a bit more than petrodiesel). Testing of pure, quality B20 by the various engine manufacturers have shown that if the fuel is made right there is no problem.
All my biodiesel has been purchased from stations owned by local fuel distributors in farming areas. These people are probably very conscientious about fuel quality, especially since they mostly sell to repeat customers and would be out of business if those customers stopped using them. One of the stations I use the most has very prominent water filters on the base of the pump where the hose comes out - this probably contributes to my lack of problems with their B20. In other words, I would hesitate to buy B20 from a station that is mostly a convenience store with a little bit of fuel sales on the side.
