Trip computers are notoriously jumpy because mpg is directly relative to throttle position and load. its not a fault. if the reading is steady when u hold accelerator position and gear then its working just fine. mpg will change as gears and accelerator position change because the engine is constantly changing load requirements. in other words the more u put ur foot down the more the reading changes.

Ok guys here is my thought about what I've read about your problem. First go to and get "Factory Service Manuel" for your 2001 DeVille! they are $150.00 but worth every penny. And don't let anybody work on your car with out this Manuel, period. No other manual will work! don't even think about Chilton, because they don't even touch the info you need. As far a dead battery, don"t ever just jump start a dead battery, instead remove the cables and charge it! Start you car after it is ready. because you chance blowing the ECM! As far as the other guy told you about the "ghost" readings, its true, the computer has nothing to report. But your car is very complicated even for the most top notch mechanic! that is why you need the FSM, because it contains all the tricks and info you need to know about. For example did you know that your cruse control will not operate if you have engine faults? In some situations you know even may not need a meter to plug in cause there is a chance that you can retrieve your engine fault codes just by suppling the combinations of switches. But the FSM can tell you that. let me tell stress to you, get the FSM and when you have a problem, then diagnose the problem your self. Then let a mechanic do only what you tell him to do. If anything else gets touched then it's on his Dime.

I have a 2004 jeep cherokee 2.8 crd and i am finding it ******* diesel . im only getting 19 mpg where im told i should b getting 25-30mpg .just wondering if anyone has come across this problem

If you own a cherokee 2.8crd in UK, the fuel consumption readout will be in miles per US gallon.To convert this reading to imperial galls multiply by1.2. Example;20mpg showing on the readout is actually 24 mpg imperial.
