Attention owner's of 2000-2001 Quad Cab V6 3.9L 5 speed's.
There is currently a problem with this combination of engine/tranmission. At 2400 rpm the engine hesitates and some times back fires.
Here is how to test for this condition:
On a flat road with very few bumps, in first gear start to accelerate (as if driving a big rig pulling 10 tons) with out shifting before 3000 rpm. As the engine cross's over the 2300-2400 rpm range the engine will hesitate for just a brief second. It will feel as if you have been rear ended or as if some had turned the fuel off. Every now and then under the same conditions the engine will back fire in the headers do to un burnt fuel in the headers and valve over lap casing the fuel to be ignited in the headers.
Repeat this test several times to confirm the problem. This test is best performed with a cold engine on a cold morning. Although this problem is still there after driving on the highway for extended periods of time, but is much harder to detect.
I have had this problem being looked at almost since the truck was new, and the dealer, west coast service tech and Chrysler Engineering can not find out what the problem is. If you find (and you will) that you have this condition occuring with your truck please inform your local dealer and have them contact Chrysler Engineering informing them of the problem as well. The more complaints about this condition the sooner it will be resolved by Chrysler/Dodge.
Please post your results to this test and to the information that is given to you by your local dealer.
Thanks for taking the time to perform this test and to posting any information you may have.
