My 06 Durango kicks when i let off the gas while cruising between 45-55 mph. It does it much more frequently now. AAMCO recommended a Trani service with all new fluids. This did not help. My Dodge gets all its scheduled maintanace so im very puzzeled. I did add an Airaid air intake, throttle spacer, and spintech exhaust shortly after buying her 4 years ago.
What should I check for, I dont want to spend money on repairs that dont repair.

 

Maybe the motor mounts? Do any codes show up?

My K&N FIPK2 CAI required that I move the CC bracket, cables, etc. If you too had to move things, check there first.

No codes showed up, Ill look under the hood for loose wires.

 

Have you ever changed the fuel filter?

 

You don't change the fuel filter... ever.
The fuel pump will fail before the filter needs attention.

My 06 D has the same kick, but it is not that noticeable. Have thought it was the MDS turning off 4 of the cylinders of the hemi, since this is my first D and have had it only a month.

 

THe MDS system does not really turn off four of the eight cylinders, it just does not use them for combustion. It uses air to pressurize the cylinders so that the cylinder walls are oiled. The pistons are attached to the crank with connecting rods and they can not be disconnected without taking the engine apart,

Yeah, I know it's in the tank, but those are the exact same symptoms I had on a Ford Ranger, and it was a clogged fuel filter.

Sounds like a fuel delivery problem to me, but who knows...

 

I took her to a second mechanic, they recommended i try a different gas station. Also my front brakes and rotors were done so i replaced them. Between all this and the service to the trani, the kick has diminished. It's still there but only slightly.
