Force problem Jeep Grand Cherockee 3.1

Good morning friends. I have a problem with a Grand Cherockee 3.1 TD Limited of the year 2000.The Calleje car is going well, but when you leave the road it is as if it runs out of strength and does not take speed and less when a uphill comes up, causing the automatic change to reduce too much and revolutionize a lot. Callejeando the change changes normally without any problem. Someone would have the repair manual of this car or idea of ​​what can happen to you. Thank you very much friends.

The diesel filter may have dirty, and since it does not see enough diesel the car does not pull. Replace the filter and have how it goes !!

Your problems can be several, one the needle injector, check that its resistance is 100 ohms approx, then you have the flow rate, you must also check the electric vavula of the turbo and the empty tubes.
